## Introduction

cmake-modules - Reference of available CMake modules.

## Description

The "cmake" executable is the CMake command-line interface. It may be used to configure projects in scripts. Project configuration settings may be specified on the command line with the -D option. The -i option will cause cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.

The following modules are provided with CMake. They can be used with INCLUDE(ModuleName).

      CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake. Using these modules you can check the computer system for installed software packages, features of the compiler and the existance of headers to name just a few.

- `AddFileDependencies`: ADD_FILE_DEPENDENCIES(source_file depend_files...)

  Adds the given files as dependencies to source_file

- `BundleUtilities`: Functions to help assemble a standalone bundle application.

  A collection of CMake utility functions useful for dealing with .app bundles on the Mac and bundle-like directories on any OS.

  The following functions are provided by this module:

         fixup_bundle
         copy_and_fixup_bundle
         verify_app
         get_bundle_main_executable
         get_dotapp_dir
         get_bundle_and_executable
         get_bundle_all_executables
         get_item_key
         clear_bundle_keys
         set_bundle_key_values
         get_bundle_keys
         copy_resolved_item_into_bundle
         copy_resolved_framework_into_bundle
         fixup_bundle_item
         verify_bundle_prerequisites
         verify_bundle_symlinks

  Requires CMake 2.6 or greater because it uses function, break and PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

        FIXUP_BUNDLE(<app> <libs> <dirs>)

  Fix up a bundle in-place and make it standalone, such that it can be drag-n-drop copied to another machine and run on that machine as long as all of the system libraries are compatible.

  If you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins)

  Gather all the keys for all the executables and libraries in a bundle, and then, for each key, copy each prerequisite into the bundle. Then fix each one up according to its own list of prerequisites.

  Then clear all the keys and call verify_app on the final bundle to ensure that it is truly standalone.

        COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

  Makes a copy of the bundle <src> at location <dst> and then fixes up the new copied bundle in-place at <dst>...

        VERIFY_APP(<app>)

  Verifies that an application <app> appears valid based on running analysis tools on it. Calls "message(FATAL_ERROR" if the application is not verified.

        GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

  The result will be the full path name of the bundle's main executable file or an "error:" prefixed string if it could not be determined.

        GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

  Returns the nearest parent dir whose name ends with ".app" given the full path to an executable. If there is no such parent dir, then return a dir at the same level as the executable, named with the executable's base name and ending with ".app"

  The returned directory may or may not exist.

        GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

  Takes either a ".app" directory name or the name of an executable nested inside a ".app" directory and returns the path to the ".app" directory in <bundle_var> and the path to its main executable in <executable_var>

        GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

  Scans the given bundle recursively for all executable files and accumulates them into a variable.

        GET_ITEM_KEY(<item> <key_var>)

  Given a file (item) name, generate a key that should be unique considering the set of libraries that need copying or fixing up to make a bundle standalone. This is essentially the file name including extension with "." replaced by "_"

  This key is used as a prefix for CMake variables so that we can associate a set of variables with a given item based on its key.

        CLEAR_BUNDLE_KEYS(<keys_var>)

  Loop over the list of keys, clearing all the variables associated with each key. After the loop, clear the list of keys itself.

  Caller of get_bundle_keys should call clear_bundle_keys when done with list of keys.

        SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
                              <copyflag>)

  Add a key to the list (if necessary) for the given item. If added, also set all the variables associated with that key.

        GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

  Loop over all the executable and library files within the bundle (and given as extra <libs>) and accumulate a list of keys representing them. Set values associated with each key such that we can loop over all of them and copy prerequisite libs into the bundle and then do appropriate install_name_tool fixups.

        COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

  Copy a resolved item into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item.

        COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

  Copy a resolved framework into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item.

  By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle. By default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus the framework Resources directory.

        FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

  Get the direct/non-system prerequisites of the resolved embedded item. For each prerequisite, change the way it is referenced to the value of the _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely changing to an "@executable_path" style reference.)

  This function requires that the resolved_embedded_item be "inside" the bundle already. In other words, if you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins)

  Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM value.

  Accumulate changes in a local variable and make *one* call to install_name_tool at the end of the function with all the changes at once.

  If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be marked writable before install_name_tool tries to change them.

        VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

  Verifies that the sum of all prerequisites of all files inside the bundle are contained within the bundle or are "system" libraries, presumed to exist everywhere.

        VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

  Verifies that any symlinks found in the bundle point to other files that are already also in the bundle... Anything that points to an external file causes this function to fail the verification.

- `CMakeBackwardCompatibilityCXX`: define a bunch of backwards compatibility variables

        CMAKE_ANSI_CXXFLAGS - flag for ansi c++
        CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
        INCLUDE(TestForANSIStreamHeaders)
        INCLUDE(CheckIncludeFileCXX)
        INCLUDE(TestForSTDNamespace)
        INCLUDE(TestForANSIForScope)

- `CMakeDependentOption`: Macro to provide an option dependent on other options.

  This macro presents an option to the user only if a set of other conditions are true. When the option is not presented a default value is used, but any value set by the user is preserved for when the option is presented again. Example invocation:

        CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                               "USE_BAR;NOT USE_ZOT" OFF)

  If USE_BAR is true and USE_ZOT is false, this provides an option called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for the USE_FOO option is saved so that when the option is re-enabled it retains its old value.

- `CMakeDetermineVSServicePack`: Includes a public function for assisting users in trying to determine the

  Visual Studio service pack in use.

  Sets the passed in variable to one of the following values or an empty string if unknown.

          vc80
          vc80sp1
          vc90
          vc90sp1

  Usage: ===========================

          if(MSVC)
             include(CMakeDetermineVSServicePack)
             DetermineVSServicePack( my_service_pack )

             if( my_service_pack )
                 message(STATUS "Detected: ${my_service_pack}")
             endif()
          endif()

  ===========================

- `CMakeFindFrameworks`: helper module to find OSX frameworks
- `CMakeForceCompiler`:

  This module defines macros intended for use by cross-compiling toolchain files when CMake is not able to automatically detect the compiler identification.

  Macro CMAKE_FORCE_C_COMPILER has the following signature:

         CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

  It sets CMAKE_C_COMPILER to the given compiler and the cmake internal variable CMAKE_C_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

  Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

         CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

  It sets CMAKE_CXX_COMPILER to the given compiler and the cmake internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

  Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

         CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

  It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

  So a simple toolchain file could look like this:

         INCLUDE (CMakeForceCompiler)
         SET(CMAKE_SYSTEM_NAME Generic)
         CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
         CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

- `CMakeParseArguments`:

  CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords> <multi_value_keywords> args...)

  CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions for parsing the arguments given to that macro or function. It processes the arguments and defines a set of variables which hold the values of the respective options.

  The <options> argument contains all options for the respective macro, i.e. keywords which can be used when calling the macro without any value following, like e.g. the OPTIONAL keyword of the install() command.

  The <one_value_keywords> argument contains all keywords for this macro which are followed by one value, like e.g. DESTINATION keyword of the install() command.

  The <multi_value_keywords> argument contains all keywords for this macro which can be followed by more than one value, like e.g. the TARGETS or FILES keywords of the install() command.

  When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the keywords listed in <options>, <one_value_keywords> and <multi_value_keywords> a variable composed of the given <prefix> followed by "_" and the name of the respective keyword. These variables will then hold the respective value from the argument list. For the <options> keywords this will be TRUE or FALSE.

  All remaining arguments are collected in a variable <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see whether your macro was called with unrecognized parameters.

  As an example here a my_install() macro, which takes similar arguments as the real install() command:

         function(MY_INSTALL)
           set(options OPTIONAL FAST)
           set(oneValueArgs DESTINATION RENAME)
           set(multiValueArgs TARGETS CONFIGURATIONS)
           cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
           ...

  Assume my_install() has been called like this:

         my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

  After the cmake_parse_arguments() call the macro will have set the following variables:

         MY_INSTALL_OPTIONAL = TRUE
         MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
         MY_INSTALL_DESTINATION = "bin"
         MY_INSTALL_RENAME = "" (was not used)
         MY_INSTALL_TARGETS = "foo;bar"
         MY_INSTALL_CONFIGURATIONS = "" (was not used)
         MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

  You can the continue and process these variables.

  Keywords terminate lists of values, e.g. if directly after a one_value_keyword another recognized keyword follows, this is interpreted as the beginning of the new option. E.g. my_install(TARGETS foo DESTINATION OPTIONAL) would result in MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

- `CMakePrintSystemInformation`: print system information

  This file can be used for diagnostic purposes just include it in a project to see various internal CMake variables.

- `CMakeVerifyManifest`:

  CMakeVerifyManifest.cmake

  This script is used to verify that embeded manifests and side by side manifests for a project match. To run this script, cd to a directory and run the script with cmake -P. On the command line you can pass in versions that are OK even if not found in the .manifest files. For example, cmake -Dallow_versions=8.0.50608.0 -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest of 8.0.50608.0 to be used in a project even if that version was not found in the .manifest file.

- `CPack`: foreach generator, it then

  The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new targets to the resulting makefiles, package and package_source, which build the binary and source installers, respectively. The generated binary installers contain everything installed via CMake's INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

  For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COMPONENT argument of CMake's INSTALL command. These components can be annotated with user-friendly names and descriptions, inter-component dependencies, etc., and grouped in various ways to customize the resulting installer. See the cpack_add_* commands, described below, for more information about component-specific installations.

  The CPACK_GENERATOR variable has different meanings in different contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a *list of generators*: when run with no other arguments, CPack will iterate over that list and produce one package for each generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming a single generator*. If you need per-cpack- generator logic to control *other* cpack settings, then you need a CPACK_PROJECT_CONFIG_FILE.

  The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE. See the top level file CMakeCPackOptions.cmake.in for an example.

  If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a per-generator basis. It only need contain overrides.

  Here's how it works:

           CPACK_GENERATOR list variable (unless told to use just a
           specific one via -G on the command line...)

         - sets CPACK_GENERATOR to the one currently being iterated
         - includes the CPACK_PROJECT_CONFIG_FILE
         - produces the package for that generator

  This is the key: For each generator listed in CPACK_GENERATOR in CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to *the one currently being used* and then include the CPACK_PROJECT_CONFIG_FILE.

  Before including this CPack module in your CMakeLists.txt file, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:

         CPACK_PACKAGE_NAME - The name of the package (or application). If
         not specified, defaults to the project name.

         CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
         "Kitware").

         CPACK_PACKAGE_VERSION_MAJOR - Package major Version

         CPACK_PACKAGE_VERSION_MINOR - Package minor Version

         CPACK_PACKAGE_VERSION_PATCH - Package patch Version

         CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
         project. Used, for example, the introduction screen of a
         CPack-generated Windows installer to describe the project.

         CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
         project (only a few words).

         CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
         not including the extension. For example, cmake-2.6.1-Linux-i686.

         CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
         target system, e.g., "CMake 2.5".

         CPACK_PROJECT_CONFIG_FILE - File included at cpack time, once per
         generator after setting CPACK_GENERATOR to the actual generator
         being used. Allows per-generator setting of CPACK_* variables at
         cpack time.

         CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
         will typically be displayed to the user (often with an explicit
         "Accept" button, for graphical installers) prior to installation.

         CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
         typically describes in some detail

         CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
         welcomes users to this installer. Typically used in the graphical
         installers on Windows and Mac OS X.

         CPACK_MONOLITHIC_INSTALL - Disables the component-based
         installation mechanism, so that all components are always installed.

         CPACK_GENERATOR - List of CPack generators to use. If not
         specified, CPack will create a set of options (e.g.,
         CPACK_BINARY_NSIS) allowing the user to enable/disable individual
         generators.

         CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
         for binary installers that will be generated by the CPack
         module. Defaults to CPackConfig.cmake.

         CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
         with a text label, to be used to create Start Menu shortcuts on
         Windows. For example, setting this to the list ccmake;CMake will
         create a shortcut named "CMake" that will execute the installed
         executable ccmake.

         CPACK_STRIP_FILES - List of files to be stripped. Starting with
         CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
         enables stripping of all files (a list of files evaluates to TRUE
         in CMake, so this change is compatible).

  The following CPack variables are specific to source packages, and will not affect binary packages:

         CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
         e.g., cmake-2.6.1

         CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
         will be stripped. Starting with CMake 2.6.0
         CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
         stripping of all files (a list of files evaluates to TRUE in CMake,
         so this change is compatible).

         CPACK_SOURCE_GENERATOR - List of generators used for the source
         packages. As with CPACK_GENERATOR, if this is not specified then
         CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
         allowing users to select which packages will be generated.

         CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
         configuration file for source installers that will be generated by
         the CPack module. Defaults to CPackSourceConfig.cmake.

         CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
         that won't be packaged when building a source package. This is a
         list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

  The following variables are specific to the DragNDrop installers built on Mac OS X:

         CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
         image. Defaults to CPACK_PACKAGE_FILE_NAME.

         CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
         (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
         bzip2-compressed). Refer to hdiutil(1) for more information on
         other available formats.

         CPACK_DMG_DS_STORE - Path to a custom .DS_Store file which e.g.
         can be used to specify the Finder window position/geometry and
         layout (such as hidden toolbars, placement of the icons etc.).
         This file has to be generated by the Finder (either manually or
         through OSA-script) using a normal folder from which the .DS_Store
         file can then be extracted.

         CPACK_DMG_BACKGROUND_IMAGE - Path to an image file which is to be
         used as the background for the Finder Window when the disk image
         is opened.  By default no background image is set. The background
         image is applied after applying the custom .DS_Store file.

         CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
         operate on disk image files on Mac OS X. This variable can be used
         to override the automatically detected command (or specify its
         location if the auto-detection fails to find it.)

         CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
         extended attributes on files and directories on Mac OS X. This
         variable can be used to override the automatically detected
         command (or specify its location if the auto-detection fails to
         find it.)

         CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
         resources on Mac OS X. This variable can be used to override the
         automatically detected command (or specify its location if the
         auto-detection fails to find it.)

  Installers built on Mac OS X using the Bundle generator use the aforementioned DragNDrop variables, plus the following Bundle-specific parameters:

         CPACK_BUNDLE_NAME - The name of the generated bundle.  This
         appears in the OSX finder as the bundle name.  Required.

         CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
         as the Info.plist for the generated bundle.  This assumes that
         the caller has generated or specified their own Info.plist file.
         Required.

         CPACK_BUNDLE_ICON - Path to an OSX icns file that will be used as
         the icon for the generated bundle.  This is the icon that appears
         in the OSX finder for the bundle, and in the OSX dock when the
         bundle is opened.  Required.

         CPACK_BUNDLE_STARTUP_SCRIPT - Path to an executable or script that
         will be run whenever an end-user double-clicks the generated bundle
         in the OSX Finder.  Optional.

  The following variables are specific to the graphical installers built on Windows using the Nullsoft Installation System.

         CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
         installing this project.

         CPACK_NSIS_INSTALL_ROOT - The default installation directory presented
         to the end user by the NSIS installer is under this root dir. The full
         directory presented to the end user is:
         ${CPACK_NSIS_INSTALL_ROOT}/${CPACK_PACKAGE_INSTALL_DIRECTORY}

         CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
         install program.

         CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
         uninstall program.

         CPACK_PACKAGE_ICON - A branding image that will be displayed inside
         the installer.

         CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
         be added to the install Section.

         CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
         be added to the uninstall Section.

         CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
         NSIS SetCompressor command.

         CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
         will appear in the installer that will allow the user to choose
         whether the program directory should be added to the system PATH
         variable.

         CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
         the Windows Add/Remove Program control panel

         CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
         installing your application.

         CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
         information about your application.

         CPACK_NSIS_CONTACT - Contact information for questions and comments
         about the installation process.

         CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
         creating start menu shortcuts.

         CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
         uninstall start menu shortcuts.

         CPACK_NSIS_EXECUTABLES_DIRECTORY - Creating NSIS start menu links
         assumes that they are in 'bin' unless this variable is set.
         For example, you would set this to 'exec' if your executables are
         in an exec directory.

         CPACK_NSIS_MUI_FINISHPAGE_RUN - Specify an executable to add an option
         to run on the finish page of the NSIS installer.

  The following variable is specific to installers build on Mac OS X using PackageMaker:

         CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
         resulting PackageMaker archive should be compatible
         with. Different versions of Mac OS X support different
         features. For example, CPack can only build component-based
         installers for Mac OS X 10.4 or newer, and can only build
         installers that download component son-the-fly for Mac OS X 10.5
         or newer. If left blank, this value will be set to the minimum
         version of Mac OS X that supports the requested features. Set this
         variable to some value (e.g., 10.4) only if you want to guarantee
         that your installer will work on that version of Mac OS X, and
         don't mind missing extra features available in the installer
         shipping with later versions of Mac OS X.

  The following variables are for advanced uses of CPack:

         CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
         project is CMake project. Defaults to the value of CMAKE_GENERATOR;
         few users will want to change this setting.

         CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
         what project to install. The four values are: Build directory,
         Project Name, Project Component, Directory. If omitted, CPack will
         build an installer that installers everything.

         CPACK_SYSTEM_NAME - System name, defaults to the value of
         ${CMAKE_SYSTEM_NAME}.

         CPACK_PACKAGE_VERSION - Package full version, used internally. By
         default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
         CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

         CPACK_TOPLEVEL_TAG - Directory for the installed files.

         CPACK_INSTALL_COMMANDS - Extra commands to install components.

         CPACK_INSTALL_DIRECTORIES - Extra directories to install.

  Component-specific installation allows users to select specific sets of components to install during the install process. Installation components are identified by the COMPONENT argument of CMake's INSTALL commands, and should be further described by the following CPack commands:

         cpack_add_component - Describes a CPack installation component
         named by the COMPONENT argument to a CMake INSTALL command.

           cpack_add_component(compname
                               [DISPLAY_NAME name]
                               [DESCRIPTION description]
                               [HIDDEN | REQUIRED | DISABLED ]
                               [GROUP group]
                               [DEPENDS comp1 comp2 ... ]
                               [INSTALL_TYPES type1 type2 ... ]
                               [DOWNLOADED]
                               [ARCHIVE_FILE filename])

         The cmake_add_component command describes an installation
         component, which the user can opt to install or remove as part of
         the graphical installation process. compname is the name of the
         component, as provided to the COMPONENT argument of one or more
         CMake INSTALL commands.

         DISPLAY_NAME is the displayed name of the component, used in
         graphical installers to display the component name. This value can
         be any string.

         DESCRIPTION is an extended description of the component, used in
         graphical installers to give the user additional information about
         the component. Descriptions can span multiple lines using "\n" as
         the line separator. Typically, these descriptions should be no
         more than a few lines long.

         HIDDEN indicates that this component will be hidden in the
         graphical installer, so that the user cannot directly change
         whether it is installed or not.

         REQUIRED indicates that this component is required, and therefore
         will always be installed. It will be visible in the graphical
         installer, but it cannot be unselected. (Typically, required
         components are shown greyed out).

         DISABLED indicates that this component should be disabled
         (unselected) by default. The user is free to select this component
         for installation, unless it is also HIDDEN.

         DEPENDS lists the components on which this component depends. If
         this component is selected, then each of the components listed
         must also be selected. The dependency information is encoded
         within the installer itself, so that users cannot install
         inconsitent sets of components.

         GROUP names the component group of which this component is a
         part. If not provided, the component will be a standalone
         component, not part of any component group. Component groups are
         described with the cpack_add_component_group command, detailed
         below.

         INSTALL_TYPES lists the installation types of which this component
         is a part. When one of these installations types is selected, this
         component will automatically be selected. Installation types are
         described with the cpack_add_install_type command, detailed below.

         DOWNLOADED indicates that this component should be downloaded
         on-the-fly by the installer, rather than packaged in with the
         installer itself. For more information, see the cpack_configure_downloads
         command.

         ARCHIVE_FILE provides a name for the archive file created by CPack
         to be used for downloaded components. If not supplied, CPack will
         create a file with some name based on CPACK_PACKAGE_FILE_NAME and
         the name of the component. See cpack_configure_downloads for more
         information.

         cpack_add_component_group - Describes a group of related CPack
         installation components.

           cpack_add_component_group(groupname
                                    [DISPLAY_NAME name]
                                    [DESCRIPTION description]
                                    [PARENT_GROUP parent]
                                    [EXPANDED]
                                    [BOLD_TITLE])

         The cpack_add_component_group describes a group of installation
         components, which will be placed together within the listing of
         options. Typically, component groups allow the user to
         select/deselect all of the components within a single group via a
         single group-level option. Use component groups to reduce the
         complexity of installers with many options. groupname is an
         arbitrary name used to identify the group in the GROUP argument of
         the cpack_add_component command, which is used to place a
         component in a group. The name of the group must not conflict with
         the name of any component.

         DISPLAY_NAME is the displayed name of the component group, used in
         graphical installers to display the component group name. This
         value can be any string.

         DESCRIPTION is an extended description of the component group,
         used in graphical installers to give the user additional
         information about the components within that group. Descriptions
         can span multiple lines using "\n" as the line
         separator. Typically, these descriptions should be no more than a
         few lines long.

         PARENT_GROUP, if supplied, names the parent group of this group.
         Parent groups are used to establish a hierarchy of groups,
         providing an arbitrary hierarchy of groups.

         EXPANDED indicates that, by default, the group should show up as
         "expanded", so that the user immediately sees all of the
         components within the group. Otherwise, the group will initially
         show up as a single entry.

         BOLD_TITLE indicates that the group title should appear in bold,
         to call the user's attention to the group.

         cpack_add_install_type - Add a new installation type containing a
         set of predefined component selections to the graphical installer.

           cpack_add_install_type(typename
                                  [DISPLAY_NAME name])

         The cpack_add_install_type command identifies a set of preselected
         components that represents a common use case for an
         application. For example, a "Developer" install type might include
         an application along with its header and library files, while an
         "End user" install type might just include the application's
         executable. Each component identifies itself with one or more
         install types via the INSTALL_TYPES argument to
         cpack_add_component.

         DISPLAY_NAME is the displayed name of the install type, which will
         typically show up in a drop-down box within a graphical
         installer. This value can be any string.

         cpack_configure_downloads - Configure CPack to download selected
         components on-the-fly as part of the installation process.

           cpack_configure_downloads(site
                                     [UPLOAD_DIRECTORY dirname]
                                     [ALL]
                                     [ADD_REMOVE|NO_ADD_REMOVE])

         The cpack_configure_downloads command configures installation-time
         downloads of selected components. For each downloadable component,
         CPack will create an archive containing the contents of that
         component, which should be uploaded to the given site. When the
         user selects that component for installation, the installer will
         download and extract the component in place. This feature is
         useful for creating small installers that only download the
         requested components, saving bandwidth. Additionally, the
         installers are small enough that they will be installed as part of
         the normal installation process, and the "Change" button in
         Windows Add/Remove Programs control panel will allow one to add or
         remove parts of the application after the original
         installation. On Windows, the downloaded-components functionality
         requires the ZipDLL plug-in for NSIS, available at:

           http://nsis.sourceforge.net/ZipDLL_plug-in

         On Mac OS X, installers that download components on-the-fly can
         only be built and installed on system using Mac OS X 10.5 or
         later.

         The site argument is a URL where the archives for downloadable
         components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
         All of the archives produced by CPack should be uploaded to that location.

         UPLOAD_DIRECTORY is the local directory where CPack will create the
         various archives for each of the components. The contents of this
         directory should be uploaded to a location accessible by the URL given
         in the site argument. If omitted, CPack will use the directory
         CPackUploads inside the CMake binary directory to store the generated
         archives.

         The ALL flag indicates that all components be downloaded. Otherwise, only
         those components explicitly marked as DOWNLOADED or that have a specified
         ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
         ADD_REMOVE (unless NO_ADD_REMOVE is specified).

         ADD_REMOVE indicates that CPack should install a copy of the installer
         that can be called from Windows' Add/Remove Programs dialog (via the
         "Modify" button) to change the set of installed components. NO_ADD_REMOVE
         turns off this behavior. This option is ignored on Mac OS X.

- `CPackDeb`: The builtin (binary) CPack Deb generator (Unix only)

  CPackDeb may be used to create Deb package using CPack. CPackDeb is a CPack generator thus it uses the CPACK_XXX variables used by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration. CPackDeb generator should work on any linux host but it will produce better deb package when Debian specific tools 'dpkg-xxx' are usable on the build system.

  CPackDeb has specific features which are controlled by the specifics CPACK_DEBIAN_XXX variables.You'll find a detailed usage on the wiki:

        http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29

  However as a handy reminder here comes the list of specific variables:

  CPACK_DEBIAN_PACKAGE_NAME

           better package dependency list.
           You may need set CMAKE_INSTALL_RPATH toi appropriate value
           if you use this feature, because if you don't dpkg-shlibdeps
           may fail to find your own shared libs.

  CPACK_DEBIAN_PACKAGE_BREAKS

           Mandatory : NO
           Default   : -
           see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
           When one binary package declares that it breaks another, dpkg will refuse to allow the
           package which declares Breaks be installed unless the broken package is deconfigured first,
           and it will refuse to allow the broken package to be reconfigured.

  CPACK_DEBIAN_PACKAGE_CONFLICTS

           Mandatory : NO

  CPACK_DEBIAN_PACKAGE_REPLACES

           Mandatory : NO
           Default   : -
           see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
           Packages can declare in their control file that they should overwrite
           files in certain other packages, or completely replace other packages.

- `CPackRPM`: The builtin (binary) CPack RPM generator (Unix only)

  CPackRPM may be used to create RPM package using CPack. CPackRPM is a CPack generator thus it uses the CPACK_XXX variables used by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration

  However CPackRPM has specific features which are controlled by the specifics CPACK_RPM_XXX variables. You'll find a detailed usage on the wiki:

        http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

  However as a handy reminder here comes the list of specific variables:

        CPACK_RPM_PACKAGE_SUMMARY
           Mandatory : YES
           Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
           The RPM package summary
        CPACK_RPM_PACKAGE_NAME
           Mandatory : YES
           Default   : CPACK_PACKAGE_NAME
           The RPM package name
        CPACK_RPM_PACKAGE_VERSION
           Mandatory : YES
           Default   : CPACK_PACKAGE_VERSION
           The RPM package version
        CPACK_RPM_PACKAGE_ARCHITECTURE
           Mandatory : NO
           Default   : -
           The RPM package architecture. This may be set to "noarch" if you
           know you are building a noarch package.
        CPACK_RPM_PACKAGE_RELEASE
           Mandatory : YES
           Default   : 1
           The RPM package release. This is the numbering of the RPM package
           itself, i.e. the version of the packaging and not the version of the
           content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
           value if the previous packaging was buggy and/or you want to put here
           a fancy Linux distro specific numbering.
        CPACK_RPM_PACKAGE_LICENSE
           Mandatory : YES
           Default   : "unknown"
           The RPM package license policy.
        CPACK_RPM_PACKAGE_GROUP
           Mandatory : YES
           Default   : "unknown"
           The RPM package group.
        CPACK_RPM_PACKAGE_VENDOR

           Default   : CPACK_PACKAGE_VENDOR if set or "unknown"
           The RPM package vendor.
        CPACK_RPM_PACKAGE_URL
           Mandatory : NO
           Default   : -
           The projects URL.
        CPACK_RPM_PACKAGE_DESCRIPTION
           Mandatory : YES
           Default   : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
        CPACK_RPM_COMPRESSION_TYPE
           Mandatory : NO
           Default   : -
           May be used to override RPM compression type to be used
           to build the RPM. For example some Linux distribution now default
           to lzma or xz compression whereas older cannot use such RPM.
           Using this one can enforce compression type to be used.
           Possible value are: lzma, xz, bzip2 and gzip.
        CPACK_RPM_PACKAGE_REQUIRES
           Mandatory : NO
           Default   : -
           May be used to set RPM dependencies (requires).
           Note that you must enclose the complete requires string between quotes,
           for example:
           set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
        CPACK_RPM_PACKAGE_SUGGESTS
           Mandatory : NO
           Default   : -
           May be used to set weak RPM dependencies (suggests).
           Note that you must enclose the complete requires string between quotes.
        CPACK_RPM_PACKAGE_PROVIDES
           Mandatory : NO
           Default   : -
           May be used to set RPM dependencies (provides).
        CPACK_RPM_PACKAGE_OBSOLETES
           Mandatory : NO
           Default   : -
           May be used to set RPM packages that are obsoleted by this one.
        CPACK_RPM_PACKAGE_RELOCATABLE
           Mandatory : NO
           Default   : CPACK_PACKAGE_RELOCATABLE
           If this variable is set to TRUE or ON CPackRPM will try
           to build a relocatable RPM package. A relocatable RPM may
           be installed using rpm --prefix or --relocate in order to
           install it at an alternate place see rpm(8).
           Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
           If CPACK_SET_DESTDIR is set then you will get a warning message
           but if there is file installed with absolute path you'll get
           unexpected behavior.
        CPACK_RPM_SPEC_INSTALL_POST
           Mandatory : NO
           Default   : -
           May be used to set an RPM post-install command inside the spec file.
           For example setting it to "/bin/true" may be used to prevent
           rpmbuild to strip binaries.
        CPACK_RPM_SPEC_MORE_DEFINE
           Mandatory : NO
           Default   : -
           May be used to add any %define lines to the generated spec file.
        CPACK_RPM_PACKAGE_DEBUG
           Mandatory : NO
           Default   : -
           May be set when invoking cpack in order to trace debug information
           during CPack RPM run. For example you may launch CPack like this
           cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
        CPACK_RPM_USER_BINARY_SPECFILE
           Mandatory : NO
           Default   : -
           May be set by the user in order to specify a USER binary spec file
           to be used by CPackRPM instead of generating the file.
           The specified file will be processed by CONFIGURE_FILE( @ONLY).
        CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE
           Mandatory : NO
           Default   : -
           If set CPack will generate a template for USER specified binary
           spec file and stop with an error. For example launch CPack like this
           cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
           The user may then use this file in order to hand-craft is own
           binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
        CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
        CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
           Mandatory : NO
           Default   : -
           May be used to embbed a pre (un)installation script in the spec file.
           The refered script file(s) will be read and directly
           put after the %pre or %preun section
           One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
        CPACK_RPM_POST_INSTALL_SCRIPT_FILE
        CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
           Mandatory : NO
           Default   : -
           May be used to embbed a post (un)installation script in the spec file.
           The refered script file(s) will be read and directly
           put after the %post or %postun section
           One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
        CPACK_RPM_CHANGELOG_FILE
           Mandatory : NO
           Default   : -
           May be used to embbed a changelog in the spec file.
           The refered file will be read and directly  put after the %changelog
           section.

- `CTest`: Configure a project for testing with CTest/CDash

  Include this module in the top CMakeLists.txt file of a project to enable testing with CTest and dashboard submissions to CDash:

         project(MyProject)
         ...
         include(CTest)

  The module automatically creates a BUILD_TESTING option that selects whether to enable testing support (ON by default). After including the module, use code like

         if(BUILD_TESTING)
           # ... CMake code to create tests ...
         endif()

  to creating tests when testing is enabled.

  To enable submissions to a CDash server, create a CTestConfig.cmake file at the top of the project with content such as

         set(CTEST_PROJECT_NAME "MyProject")
         set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
         set(CTEST_DROP_METHOD "http")
         set(CTEST_DROP_SITE "my.cdash.org")
         set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
         set(CTEST_DROP_SITE_CDASH TRUE)

  (the CDash server can provide the file to a project administrator who configures 'MyProject'). Settings in the config file are shared by both this CTest module and the CTest command-line tool's dashboard script mode (ctest -S).

  While building a project for submission to CDash, CTest scans the build output for errors and warnings and reports them with surrounding context from the build log. This generic approach works for all build tools, but does not give details about the command invocation that produced a given problem. One may get more detailed reports by adding

         set(CTEST_USE_LAUNCHERS 1)

  to the CTestConfig.cmake file. When this option is enabled, the CTest module tells CMake's Makefile generators to invoke every command in the generated build system through a CTest launcher program. (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile generators.) During a manual build each launcher transparently runs the command it wraps. During a CTest-driven build for submission to CDash each launcher reports detailed information when its command fails or warns. (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but also adds the launcher overhead even for manual builds. One may instead set it in a CTest dashboard script and add it to the CMake cache for the build tree.)

        CMAKE_REQUIRED_INCLUDES = list of include directories

- `CheckLibraryExists`: Check if the function exists.

  CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

  CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)

        STRUCT - the name of the struct or class you are interested in
        MEMBER - the member which existence you want to check
        HEADER - the header(s) where the prototype should be declared
        VARIABLE - variable to store the result

- `CheckSymbolExists`: Check if a symbol exists as a function, variable, or macro

  CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

  Check that the <symbol> is available after including given header <files> and store the result in a <variable>. Specify the list of files in one argument as a semicolon-separated list.

  If the header files define the symbol as a macro it is considered available and assumed to work. If the header files declare the symbol as a function or variable then the symbol must also be available for linking. If the symbol is a type or enum value it will not be recognized (consider using CheckTypeSize or CheckCSourceCompiles).

  The following variables may be set before calling this macro to modify the way the check is run:

        CMAKE_REQUIRED_FLAGS = string of compile command line flags

        CMAKE_REQUIRED_INCLUDES = list of include directories
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link

- `CheckTypeSize`: Check sizeof a type

        CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

  Check if the type exists and determine its size. On return, "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}" holds one of the following:

         <size> = type has non-zero size <size>
         "0"    = type has arch-dependent size (see below)
         ""     = type does not exist

  Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code to define the macro "${VARIABLE}" to the size of the type, or leave the macro undefined if the type does not exist.

  The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has multiple architectures for building OS X universal binaries. This indicates that the type size varies across architectures. In this case "${VARIABLE}_CODE" contains C preprocessor tests mapping from each architecture macro to the corresponding type size. The list of architecture macros is stored in "${VARIABLE}_KEYS", and the value for each key is stored in "${VARIABLE}-${KEY}".

  If the BUILTIN_TYPES_ONLY option is not given, the macro checks for headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size check automatically includes the available headers, thus supporting checks of types defined in the headers.

  The following variables may be set before calling this macro to modify the way the check is run:

        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_INCLUDES = list of include directories
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link
        CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include

- `CheckVariableExists`: Check if the variable exists.

        CHECK_VARIABLE_EXISTS(VAR VARIABLE)

        VAR      - the name of the variable
        VARIABLE - variable to store the result

  This macro is only for C variables.

  The following variables may be set before calling this macro to modify the way the check is run:

        CMAKE_REQUIRED_FLAGS = string of compile command line flags
        CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
        CMAKE_REQUIRED_LIBRARIES = list of libraries to link

- `Dart`: Configure a project for testing with CTest or old Dart Tcl Client

  This file is the backwards-compatibility version of the CTest module. It supports using the old Dart 1 Tcl client for driving dashboard submissions as well as testing with CTest. This module should be included in the CMakeLists.txt file at the top of a project. Typical usage:

        INCLUDE(Dart)
        IF(BUILD_TESTING)
          # ... testing related CMake code ...
        ENDIF(BUILD_TESTING)

  The BUILD_TESTING option is created by the Dart module to determine whether testing support should be enabled. The default is ON.

- `Documentation`: DocumentationVTK.cmake

  This file provides support for the VTK documentation framework. It relies on several tools (Doxygen, Perl, etc).

- `ExternalProject`: Create custom targets to build projects in external trees

          )

  The *_DIR options specify directories for the project, with default directories computed as follows. If the PREFIX option is given to ExternalProject_Add() or the EP_PREFIX directory property is set, then an external project is built and installed under the specified prefix:

         TMP_DIR      = <prefix>/tmp
         STAMP_DIR    = <prefix>/src/<name>-stamp
         DOWNLOAD_DIR = <prefix>/src
         SOURCE_DIR   = <prefix>/src/<name>
         BINARY_DIR   = <prefix>/src/<name>-build
         INSTALL_DIR  = <prefix>

  Otherwise, if the EP_BASE directory property is set then components of an external project are stored under the specified base:

         TMP_DIR      = <base>/tmp/<name>
         STAMP_DIR    = <base>/Stamp/<name>
         DOWNLOAD_DIR = <base>/Download/<name>
         SOURCE_DIR   = <base>/Source/<name>
         BINARY_DIR   = <base>/Build/<name>
         INSTALL_DIR  = <base>/Install/<name>

  If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is to set PREFIX to "<name>-prefix". Relative paths are interpreted with respect to the build directory corresponding to the source directory in which ExternalProject_Add is invoked.

  If SOURCE_DIR is explicitly set to an existing directory the project will be built from it. Otherwise a download step must be specified using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options. The URL option may refer locally to a directory or source tarball, or refer to a remote tarball (e.g. http://.../src.tgz).

  The 'ExternalProject_Add_Step' function adds a custom step to an external project:

        ExternalProject_Add_Step(<name> <step> # Names of project and custom step
          [COMMAND cmd...]        # Command line invoked by this step
          [COMMENT "text..."]     # Text printed when step executes
          [DEPENDEES steps...]    # Steps on which this step depends
          [DEPENDERS steps...]    # Steps that depend on this step
          [DEPENDS files...]      # Files on which this step depends
          [ALWAYS 1]              # No stamp file, step always runs
          [WORKING_DIRECTORY dir] # Working directory for command
          [LOG 1]                 # Wrap step in script to log output
          )

  The command line, comment, and working directory of every standard and custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>, <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

  The 'ExternalProject_Get_Property' function retrieves external project target properties:

        ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

  It stores property values in variables of the same name. Property names correspond to the keyword argument names of 'ExternalProject_Add'.

  The 'ExternalProject_Add_StepTargets' function generates custom targets for the steps listed:

        ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

  If STEP_TARGETS is set then ExternalProject_Add_StepTargets is automatically called at the end of matching calls to ExternalProject_Add_Step. Pass STEP_TARGETS explicitly to individual ExternalProject_Add calls, or implicitly to all ExternalProject_Add calls by setting the directory property EP_STEP_TARGETS.

  If STEP_TARGETS is not set, clients may still manually call ExternalProject_Add_StepTargets after calling ExternalProject_Add or ExternalProject_Add_Step.

  This functionality is provided to make it easy to drive the steps independently of each other by specifying targets on build command lines. For example, you may be submitting to a sub-project based dashboard, where you want to drive the configure portion of the build, then submit to the dashboard, followed by the build portion, followed by tests. If you invoke a custom target that depends on a step halfway through the step dependency chain, then all the previous steps will also run to ensure everything is up to date.

  For example, to drive configure, build and test steps independently for each ExternalProject_Add call in your project, write the following line prior to any ExternalProject_Add calls in your CMakeLists file:

         set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)

- `FeatureSummary`: Macros for generating a summary of enabled/disabled features

  This module provides the macros feature_summary(), set_package_info() and add_feature_info(). For compatiblity it also still provides set_feature_info(), print_enabled_features() and print_disabled_features.

  These macros can be used to generate a summary of enabled and disabled packages and/or feature for a build tree:

          -- Enabled features:
          LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>
          PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
          -- Disabled features:
          Lua51 , The Lua scripting language. , <http://www.lua.org>
          Foo , Foo provides cool stuff.

          FEATURE_SUMMARY( [FILENAME <file>]
                           [APPEND]
                           [VAR <variable_name>]
                           [DESCRIPTION "Found packages:"]
                           WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
                                | ENABLED_FEATURES | DISABLED_FEATURES]
                         )

  The FEATURE_SUMMARY() macro can be used to print information about enabled or disabled features or packages of a project. By default, only the names of the features/packages will be printed and their required version when one was specified. Use SET_FEATURE_INFO() to add more useful information, like e.g. a download URL for the respective package.

  The WHAT option is the only mandatory option. Here you specify what information will be printed:

          ENABLED_FEATURES: the list of all features and packages which are enabled,
                            excluding the QUIET packages
          DISABLED_FEATURES: the list of all features and packages which are disabled,
                             excluding the QUIET packages
          PACKAGES_FOUND: the list of all packages which have been found
          PACKAGES_NOT_FOUND: the list of all packages which have not been found
          ALL: this will give all packages which have or have not been found

  If a FILENAME is given, the information is printed into this file. If APPEND is used, it is appended to this file, otherwise the file is overwritten if it already existed. If the VAR option is used, the information is "printed" into the specified variable. If FILENAME is not used, the information is printed to the terminal. Using the DESCRIPTION option a description or headline can be set which will be printed above the actual content.

  Example 1, append everything to a file:

         feature_summary(WHAT ALL
                         FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

  Example 2, print the enabled features into the variable enabledFeaturesText:

         feature_summary(WHAT ENABLED_FEATURES
                         DESCRIPTION "Enabled Features:"
                         VAR enabledFeaturesText)
         message(STATUS "${enabledFeaturesText}")

          SET_PACKAGE_INFO(<name> <description> [<url> [<comment>] ] )

  Use this macro to set up information about the named package, which can then be displayed via FEATURE_SUMMARY(). This can be done either directly in the Find-module or in the project which uses the module after the FIND_PACKAGE() call. The features for which information can be set are added automatically by the find_package() command.

  Example for setting the info for a package:

         find_package(LibXml2)
         set_package_info(LibXml2 "XML processing library." "http://xmlsoft.org/")

          ADD_FEATURE_INFO(<name> <enabled> <description>)

  Use this macro to add information about a feature with the given <name>. <enabled> contains whether this feature is enabled or not, <description> is a text descibing the feature. The information can be displayed using feature_summary() for ENABLED_FEATURES and DISABLED_FEATURES respectively.

  Example for setting the info for a feature:

         option(WITH_FOO "Help for foo" ON)
         add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

  The following macros are provided for compatibility with previous CMake versions:

          PRINT_ENABLED_FEATURES()

  Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:")

          PRINT_DISABLED_FEATURES()

  Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:")

          SET_FEATURE_INFO(<name> <description> [<url> [<comment>] ] )

  Does the same as SET_PACKAGE_INFO(<name> <description> <url> <comment> )

- `FindALSA`: Find alsa

  Find the alsa libraries (asound)

        This module defines the following variables:
           ALSA_FOUND       - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
           ALSA_LIBRARIES   - Set when ALSA_LIBRARY is found
           ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found

           ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
           ALSA_LIBRARY     - the asound library

- `FindASPELL`: Try to find ASPELL

  Once done this will define

        ASPELL_FOUND - system has ASPELL
        ASPELL_INCLUDE_DIR - the ASPELL include directory
        ASPELL_LIBRARIES - The libraries needed to use ASPELL
        ASPELL_DEFINITIONS - Compiler switches required for using ASPELL

- `FindAVIFile`: Locate AVIFILE library and include paths

  AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for i386 machines to use various AVI codecs. Support is limited beyond Linux. Windows provides native AVI support, and so doesn't need this library. This module defines

        AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
        AVIFILE_LIBRARIES, the libraries to link against
        AVIFILE_DEFINITIONS, definitions to use when compiling
        AVIFILE_FOUND, If false, don't try to use AVIFILE

- `FindBISON`: Find bison executable and provides macros to generate custom build rules

  The module defines the following variables:

        BISON_EXECUTABLE - path to the bison program
        BISON_VERSION - version of bison
        BISON_FOUND - true if the program was found

  The minimum required version of bison can be specified using the standard CMake syntax, e.g. find_package(BISON 2.1.3)

  If bison is found, the module defines the macros:

        BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
                    [COMPILE_FLAGS <string>])

  which will create a custom rule to generate a parser. <YaccInput> is the path to a yacc file. <CodeOutput> is the name of the source file generated by bison. A header file is also be generated, and contains the token list. If COMPILE_FLAGS option is specified, the next parameter is added in the bison command line. if VERBOSE option is specified, <file> is created and contains verbose descriptions of the grammar and parser. The macro defines a set of variables:

        BISON_${Name}_DEFINED - true is the macro ran successfully
        BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
        BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
        BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
        BISON_${Name}_OUTPUTS - The sources files generated by bison
        BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

        ====================================================================
        Example:

         find_package(BISON)
         BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
         add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
        ====================================================================

- `FindBLAS`: Find BLAS library

  This module finds an installed fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/). The list of libraries searched for is taken from the autoconf macro file, acx_blas.m4 (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

  This module sets the following variables:

        BLAS_FOUND - set to true if a library implementing the BLAS interface
          is found
        BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
          and -L).
        BLAS_LIBRARIES - uncached list of libraries (using full path name) to
          link against to use BLAS
        BLAS95_LIBRARIES - uncached list of libraries (using full path name)
          to link against to use BLAS95 interface
        BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
          is found
        BLA_STATIC  if set on this determines what kind of linkage we do (static)
        BLA_VENDOR  if set checks only the specified vendor, if not set checks
           all the possibilities
        BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

  ######### ## List of vendors (BLA_VENDOR) valid in this module # ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread model, lp64 model), # Intel( older versions of mkl 32 and 64 bit), ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl

- `FindBZip2`: Try to find BZip2

  Once done this will define

        BZIP2_FOUND - system has BZip2
        BZIP2_INCLUDE_DIR - the BZip2 include directory
        BZIP2_LIBRARIES - Link these to use BZip2
        BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_

- `FindBoost`: Try to find Boost include dirs and libraries

  Usage of this module as follows:

  NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below. Due to Boost naming conventions and limitations in CMake this find module is NOT future safe with respect to Boost version numbers, and may break.

  == Using Header-Only libraries from within Boost: ==

         find_package( Boost 1.36.0 )
         if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
         endif()

  == Using actual libraries from within Boost: ==

         set(Boost_USE_STATIC_LIBS        ON)
         set(Boost_USE_MULTITHREADED      ON)
         set(Boost_USE_STATIC_RUNTIME    OFF)
         find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )

         if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
            target_link_libraries(foo ${Boost_LIBRARIES})
         endif()

  The components list needs to contain actual names of boost libraries only, such as "date_time" for "libboost_date_time". If you're using parts of Boost that contain header files only (e.g. foreach) you do not need to specify COMPONENTS.

  You should provide a minimum version number that should be used. If you provide this version number and specify the REQUIRED attribute, this module will fail if it can't find the specified or a later version. If you specify a version number this is automatically put into the considered list of version numbers and thus doesn't need to be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).

  NOTE for Visual Studio Users:

           Automatic linking is used on MSVC & Borland compilers by default when
           #including things in Boost.  It's important to note that setting
           Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
           should you need this feature.  Automatic linking typically uses static
           libraries with a few exceptions (Boost.Python is one).

           Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
           more details.  Adding a TARGET_LINK_LIBRARIES() as shown in the example
           above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
           gets set to OFF.  It is suggested you avoid automatic linking since it
           will make your application less portable.

  =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?) ============

  OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of boost version numbers that should be taken into account when searching for Boost. Unfortunately boost puts the version number into the actual filename for the libraries, so this variable will certainly be needed in the future when new Boost versions are released.

  Currently this module searches for the following version numbers: 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1, 1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0, 1.40, 1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0, 1.45, 1.45.0, 1.46, 1.46.0

  NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS you should add both 1.x and 1.x.0 as shown above. Official Boost include directories omit the 3rd version number from include paths if it is 0 although not all binary Boost releases do so.

  set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")

  ===================================== ============= ========================

  Variables used by this module, they can change the default behaviour and need to be set before calling find_package:

         Boost_USE_MULTITHREADED      Can be set to OFF to use the non-multithreaded
                                      boost libraries.  If not specified, defaults
                                      to ON.

         Boost_USE_STATIC_LIBS        Can be set to ON to force the use of the static
                                      boost libraries. Defaults to OFF.

         Boost_NO_SYSTEM_PATHS        Set to TRUE to suppress searching in system
                                      paths (or other locations outside of BOOST_ROOT
                                      or BOOST_INCLUDEDIR).  Useful when specifying
                                      BOOST_ROOT. Defaults to OFF.
                                        [Since CMake 2.8.3]

         Boost_USE_STATIC_RUNTIME     If enabled, searches for boost libraries
                                      linked against a static C++ standard library
                                      ('s' ABI tag). This option should be set to
                                      ON or OFF because the default behavior
                                      if not specified is platform dependent
                                      for backwards compatibility.
                                        [Since CMake 2.8.3]

         Boost_USE_DEBUG_PYTHON       If enabled, searches for boost libraries
                                      compiled against a special debug build of
                                      Python ('y' ABI tag). Defaults to OFF.
                                        [Since CMake 2.8.3]

         Boost_USE_STLPORT            If enabled, searches for boost libraries
                                      compiled against the STLPort standard
                                      library ('p' ABI tag). Defaults to OFF.
                                        [Since CMake 2.8.3]

         Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
                                      If enabled, searches for boost libraries
                                      compiled against the deprecated STLPort
                                      "native iostreams" feature ('n' ABI tag).
                                      Defaults to OFF.

                                      about why it failed or how to fix the problem
                                      unless this is set to TRUE or the REQUIRED

         Boost_COMPILER               Set this to the compiler suffix used by Boost
                                      (e.g. "-gcc43") if FindBoost has problems finding
                                      the proper Boost installation

         Boost_THREADAPI                When building boost.thread, sometimes the name of the
                                      library contains an additional "pthread" or "win32"
                                      string known as the threadapi.  This can happen when
                                      compiling against pthreads on Windows or win32 threads
                                      on Cygwin.  You may specify this variable and if set
                                      when FindBoost searches for the Boost threading library
                                      it will first try to match the threadapi you specify.
                                        For Example: libboost_thread_win32-mgw45-mt-1_43.a
                                      might be found if you specified "win32" here before
                                      falling back on libboost_thread-mgw45-mt-1_43.a.

         Boost_REALPATH               Resolves symbolic links for discovered boost libraries
                                      to assist with packaging.  For example, instead of
                                      Boost_SYSTEM_LIBRARY_RELEASE being resolved to
                                      "/usr/lib/libboost_system.so" it would be
                                      "/usr/lib/libboost_system.so.1.42.0" instead.
                                      This does not affect linking and should not be
                                      enabled unless the user needs this information.

- `FindBullet`: Try to find the Bullet physics engine

        This module defines the following variables

        BULLET_FOUND - Was bullet found
        BULLET_INCLUDE_DIRS - the Bullet include directories
        BULLET_LIBRARIES - Link to this, by default it includes
                           all bullet components (Dynamics,
                           Collision, LinearMath, & SoftBody)

        This module accepts the following variables

        BULLET_ROOT - Can be set to bullet install path or Windows build path

- `FindCABLE`: Find CABLE

  This module finds if CABLE is installed and determines where the include files and libraries are. This code sets the following variables:

        CABLE             the path to the cable executable
        CABLE_TCL_LIBRARY the path to the Tcl wrapper library
        CABLE_INCLUDE_DIR the path to the include directory

  To build Tcl wrappers, you should add shared library and link it to ${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an include directory.

- `FindCUDA`: Tools for building CUDA C files: libraries and build dependencies.

  This script locates the NVIDIA CUDA C tools. It should work on linux, windows, and mac and should be reasonably up to date with CUDA C releases.

  This script makes use of the standard find_package arguments of <VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an acceptable version of CUDA was found.

  The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be determined by the location of nvcc in the system path and REQUIRED is specified to find_package(). To use a different installed version of the toolkit set the environment variable CUDA_BIN_PATH before running cmake (e.g. CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring. If you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that depend on the path will be relocated.

  It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain platforms, or to use a cuda runtime not installed in the default location. In newer versions of the toolkit the cuda library is included with the graphics driver- be sure that the driver version matches what is needed by the cuda runtime version.

  The following variables affect the behavior of the macros in the script (in alphebetical order). Note that any of these flags can be changed multiple times in the same directory before calling CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX or CUDA_WRAP_SRCS.

        CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
        -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
           Note that making this different from the host code when generating object
           or C files from CUDA code just won't work, because size_t gets defined by
           nvcc in the generated source.  If you compile to PTX and then load the
           file yourself, you can mix bit sizes between device and host.

        CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
        -- Set to ON if you want the custom build rule to be attached to the source
           file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
           targets.

           This allows the user to build the target from the CUDA file; however, bad
           things can happen if the CUDA source file is added to multiple targets.
           When performing parallel builds it is possible for the custom build
           command to be run more than once and in parallel causing cryptic build
           errors.  VS runs the rules for every source file in the target, and a
           source can have only one rule no matter how many projects it is added to.
           When the rule is run from multiple targets race conditions can occur on
           the generated file.  Eventually everything will get built, but if the user
           is unaware of this behavior, there may be confusion.  It would be nice if
           this script could detect the reuse of source files across multiple targets
           and turn the option off for the user, but no good solution could be found.

        CUDA_BUILD_CUBIN (Default OFF)
        -- Set to ON to enable and extra compilation pass with the -cubin option in
           Device mode. The output is parsed and register, shared memory usage is
           printed during build.

        CUDA_BUILD_EMULATION (Default OFF for device mode)
        -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
           when CUDA_BUILD_EMULATION is TRUE.

        CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
        -- Set to the path you wish to have the generated files placed.  If it is
           blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
           Intermediate files will always be placed in
           CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

        CUDA_HOST_COMPILATION_CPP (Default ON)
        -- Set to OFF for C compilation of host code.

        CUDA_NVCC_FLAGS
        CUDA_NVCC_FLAGS_<CONFIG>
        -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
           semi-colon delimited (e.g. --compiler-options;-Wall)

        CUDA_PROPAGATE_HOST_FLAGS (Default ON)
        -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
           dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
           host compiler through nvcc's -Xcompiler flag.  This helps make the
           generated host code match the rest of the system better.  Sometimes
           certain flags give nvcc problems, and this will help you turn the flag
           propagation off.  This does not affect the flags supplied directly to nvcc
           via CUDA_NVCC_FLAGS or through the OPTION flags specified through
           CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
           shared library compilation are not affected by this flag.

        CUDA_VERBOSE_BUILD (Default OFF)
        -- Set to ON to see all the commands used when building the CUDA file.  When
           using a Makefile generator the value defaults to VERBOSE (run make
           VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
           always print the output.

  The script creates the following macros (in alphebetical order):

        CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
        -- Adds the cufft library to the target (can be any target).  Handles whether
           you are in emulation mode or not.

        CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
        -- Adds the cublas library to the target (can be any target).  Handles
           whether you are in emulation mode or not.

        CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                             [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
        -- Creates an executable "cuda_target" which is made up of the files
           specified.  All of the non CUDA C files are compiled using the standard
           build rules specified by CMAKE and the cuda files are compiled to object
           files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
           added automatically to include_directories().  Some standard CMake target
           calls can be used on the target after calling this macro
           (e.g. set_target_properties and target_link_libraries), but setting
           properties that adjust compilation flags will not affect code compiled by
           nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
           CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

        CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                          [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
        -- Same as CUDA_ADD_EXECUTABLE except that a library is created.

        CUDA_BUILD_CLEAN_TARGET()
        -- Creates a convience target that deletes all the dependency files
           generated.  You should make clean after running this target to ensure the
           dependency files get regenerated.

        CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
                      [OPTIONS ...] )
        -- Returns a list of generated files from the input source files to be used
           with ADD_LIBRARY or ADD_EXECUTABLE.

        CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
        -- Returns a list of PTX files generated from the input source files.

        CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
        -- Sets the directories that should be passed to nvcc
           (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
           files.

        CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                         [STATIC | SHARED | MODULE] [OPTIONS ...] )
        -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
           CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
           function under the hood.

           Given the list of files (file0 file1 ... fileN) this macro generates
           custom commands that generate either PTX or linkable objects (use "PTX" or
           "OBJ" for the format argument to switch).  Files that don't end with .cu
           or have the HEADER_FILE_ONLY property are ignored.

           The arguments passed in after OPTIONS are extra command line options to
           give to nvcc.  You can also specify per configuration options by
           specifying the name of the configuration followed by the options.  General
           options must preceed configuration specific options.  Not all
           configurations need to be specified, only the ones provided will be used.

              OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
              DEBUG -g
              RELEASE --use_fast_math
              RELWITHDEBINFO --use_fast_math;-g
              MINSIZEREL --use_fast_math

           For certain configurations (namely VS generating object files with
           CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
           be produced for the given cuda file.  This is because when you add the
           cuda file to Visual Studio it knows that this file produces an object file
           and will link in the resulting object file automatically.

           This script will also generate a separate cmake script that is used at
           build time to invoke nvcc.  This is for several reasons.

             1. nvcc can return negative numbers as return values which confuses
             Visual Studio into thinking that the command succeeded.  The script now
             checks the error codes and produces errors when there was a problem.

             2. nvcc has been known to not delete incomplete results when it
             encounters problems.  This confuses build systems into thinking the
             target was generated when in fact an unusable file exists.  The script
             now deletes the output files if there was an error.

             3. By putting all the options that affect the build into a file and then
             make the build rule dependent on the file, the output files will be
             regenerated when the options change.

           This script also looks at optional arguments STATIC, SHARED, or MODULE to
           determine when to target the object compilation for a shared library.
           BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
           CUDA_ADD_LIBRARY.  On some systems special flags are added for building
           objects intended for shared libraries.  A preprocessor macro,
           <target_name>_EXPORTS is defined when a shared library compilation is
           detected.

           Flags passed into add_definitions with -D or /D are passed along to nvcc.

  The script defines the following variables:

        CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
        CUDA_VERSION_MINOR    -- The minor version.
        CUDA_VERSION
        CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

        CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
        CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
                                 SDK.  This script will not directly support finding
                                 specific libraries or headers, as that isn't
                                 supported by NVIDIA.  If you want to change
                                 libraries when the path changes see the
                                 FindCUDA.cmake script for an example of how to clear
                                 these variables.  There are also examples of how to
                                 use the CUDA_SDK_ROOT_DIR to locate headers or
                                 libraries, if you so choose (at your own risk).
        CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
                                 for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
        CUDA_LIBRARIES        -- Cuda RT library.
        CUDA_CUFFT_LIBRARIES  -- Device or emulation library for the Cuda FFT
                                 implementation (alternative to:
                                 CUDA_ADD_CUFFT_TO_TARGET macro)
        CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
                                 implementation (alterative to:
                                 CUDA_ADD_CUBLAS_TO_TARGET macro).

                                         generated by CxxTest
                 input_files_to_testgen  The list of header files containing the
                                         CxxTest::TestSuite's to be included in
                                         this runner

             #==============
             Example Usage:

                 find_package(CxxTest)
                 if(CXXTEST_FOUND)
                     include_directories(${CXXTEST_INCLUDE_DIR})
                     enable_testing()

                     CXXTEST_ADD_TEST(unittest_foo foo_test.cc
                                       ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
                     target_link_libraries(unittest_foo foo) # as needed
                 endif()

                    This will (if CxxTest is found):
                    1. Invoke the testgen executable to autogenerate foo_test.cc in the
                       binary tree from "foo_test.h" in the current source directory.
                    2. Create an executable and test called unittest_foo.

            #=============
            Example foo_test.h:

                #include <cxxtest/TestSuite.h>

                class MyTestSuite : public CxxTest::TestSuite
                {
                public:
                   void testAddition( void )
                   {
                      TS_ASSERT( 1 + 1 > 1 );
                      TS_ASSERT_EQUALS( 1 + 1, 2 );
                   }
                };

- `FindCygwin`: this module looks for Cygwin

- `FindDCMTK`: find DCMTK libraries and applications

- `FindDart`: Find DART

  This module looks for the dart testing software and sets DART_ROOT to point to where it found it.

- `FindDevIL`:

  This module locates the developer's image library. http://openil.sourceforge.net/

  This module sets: IL_LIBRARIES the name of the IL library. These include the full path to the core DevIL library. This one has to be linked into the application. ILU_LIBRARIES the name of the ILU library. Again, the full path. This library is for filters and effects, not actual loading. It doesn't have to be linked if the functionality it provides is not used. ILUT_LIBRARIES the name of the ILUT library. Full path. This part of the library interfaces with OpenGL. It is not strictly needed in applications. IL_INCLUDE_DIR where to find the il.h, ilu.h and ilut.h files. IL_FOUND this is set to TRUE if all the above variables were set. This will be set to false if ILU or ILUT are not found, even if they are not needed. In most systems, if one library is found all the others are as well. That's the way the DevIL developers release it.

- `FindDoxygen`: This module looks for Doxygen and the path to Graphviz's dot

  Doxygen is a documentation generation tool. Please see http://www.doxygen.org

  This module accepts the following optional variables:

         DOXYGEN_SKIP_DOT       = If true this module will skip trying to find Dot
                                  (an optional component often used by Doxygen)

  This modules defines the following variables:

         DOXYGEN_EXECUTABLE     = The path to the doxygen command.
         DOXYGEN_FOUND          = Was Doxygen found or not?

         DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
         DOXYGEN_DOT_FOUND      = Was Dot found or not?
         DOXYGEN_DOT_PATH       = The path to dot not including the executable

- `FindEXPAT`: Find expat

  Find the native EXPAT headers and libraries.

        EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
        EXPAT_LIBRARIES    - List of libraries when using expat.
        EXPAT_FOUND        - True if expat found.

- `FindFLEX`: Find flex executable and provides a macro to generate custom build rules

  The module defines the following variables:

        FLEX_FOUND - true is flex executable is found
        FLEX_EXECUTABLE - the path to the flex executable
        FLEX_VERSION - the version of flex
        FLEX_LIBRARIES - The flex libraries

  The minimum required version of flex can be specified using the standard syntax, e.g. FIND_PACKAGE(FLEX 2.5.13)

  If flex is found on the system, the module provides the macro:

        FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

  which creates a custom command to generate the <FlexOutput> file from the <FlexInput> file. If COMPILE_FLAGS option is specified, the next parameter is added to the flex command line. Name is an alias used to get details of this custom command. Indeed the macro defines the following variables:

        FLEX_${Name}_DEFINED - true is the macro ran successfully
        FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
        alias for FlexOutput
        FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

  Flex scanners oftenly use tokens defined by Bison: the code generated by Flex depends of the header generated by Bison. This module also defines a macro:

        ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

  which adds the required dependency between a scanner and a parser where <FlexTarget> and <BisonTarget> are the first parameters of respectively FLEX_TARGET and BISON_TARGET macros.

        ====================================================================
        Example:

         find_package(BISON)
         find_package(FLEX)

         BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
         FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
         ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

         include_directories(${CMAKE_CURRENT_BINARY_DIR})
         add_executable(Foo
            Foo.cc
            ${BISON_MyParser_OUTPUTS}
            ${FLEX_MyScanner_OUTPUTS}
         )
        ====================================================================

        GETTEXT_FOUND: True if gettext has been found.

  Additionally it provides the following macros: GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )

          This will create a target "translations" which will convert the
          given input po files into the binary output mo file. If the
          ALL option is used, the translations will also be created when
          building the default target.

- `FindGit`:

- `FindHDF5`: Find HDF5, a library for reading and writing self describing array data.

  This module invokes the HDF5 wrapper compiler that should be installed alongside HDF5. Depending upon the HDF5 Configuration, the wrapper compiler is called either h5cc or h5pcc. If this succeeds, the module will then call the compiler with the -show argument to see what flags are used when compiling an HDF5 client application.

  The module will optionally accept the COMPONENTS argument. If no COMPONENTS are specified, then the find module will default to finding only the HDF5 C library. If one or more COMPONENTS are specified, the module will attempt to find the language bindings for the specified components. Currently, the only valid components are C and CXX. The module does not yet support finding the Fortran bindings. If the COMPONENTS argument is not given, the module will attempt to find only the C bindings.

  On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a static link to a dynamic link for HDF5 and all of it's dependencies. To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package.

  To provide the module with a hint about where to find your HDF5 installation, you can set the environment variable HDF5_ROOT. The Find module will then look in this path when searching for HDF5 executables, paths, and libraries.

  In addition to finding the includes and libraries required to compile an HDF5 client application, this module also makes an effort to find tools that come with the HDF5 distribution that may be useful for regression testing.

  This module will define the following variables:

        HDF5_INCLUDE_DIRS - Location of the hdf5 includes
        HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
        HDF5_DEFINITIONS - Required compiler definitions for HDF5

        HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
        HDF5_LIBRARIES - Required libraries for all requested bindings
        HDF5_FOUND - true if HDF5 was found on the system
        HDF5_LIBRARY_DIRS - the full set of library directories
        HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
        HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
        HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
        HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool

         HTML_HELP_LIBRARY      : full path to the library (htmlhelp.lib)

- `FindITK`: Find an ITK installation or build tree.
- `FindImageMagick`: Find the ImageMagick binary suite.

  This module will search for a set of ImageMagick tools specified as components in the FIND_PACKAGE call. Typical components include, but are not limited to (future versions of ImageMagick might have additional components not listed here):

        animate
        compare
        composite
        conjure

        display
        identify
        import
        mogrify
        montage
        stream

  If no component is specified in the FIND_PACKAGE call, then it only searches for the ImageMagick executable directory. This code defines the following variables:

  This module finds if Java is installed and determines where the include files and libraries are. This code sets the following variables:

        Java_JAVA_EXECUTABLE    = the full path to the Java runtime
        Java_JAVAC_EXECUTABLE   = the full path to the Java compiler
        Java_JAR_EXECUTABLE     = the full path to the Java archiver
        Java_VERSION_STRING     = Version of the package found (java version), eg. 1.6.0_12
        Java_VERSION_MAJOR      = The major version of the package found.
        Java_VERSION_MINOR      = The minor version of the package found.
        Java_VERSION_PATCH      = The patch version of the package found.
        Java_VERSION_TWEAK      = The tweak version of the package found (after '_')
        Java_VERSION            = This is set to: $major.$minor.$patch(.$tweak)

  The minimum required version of Java can be specified using the standard CMake syntax, e.g. FIND_PACKAGE(Java 1.5)

  NOTE: ${Java_VERSION} and ${Java_VERSION_STRING} are not guaranteed to be identical. For example some java version may return: Java_VERSION_STRING = 1.5.0_17 and Java_VERSION = 1.5.0.17

  another example is the Java OEM, with: Java_VERSION_STRING = 1.6.0-oem and Java_VERSION = 1.6.0

  For these components the following variables are set:

        Java_FOUND                    - TRUE if all components are found.
        Java_INCLUDE_DIRS             - Full paths to all include dirs.
        Java_LIBRARIES                - Full paths to all libraries.
        Java_<component>_FOUND        - TRUE if <component> is found.

  It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is always the variable which contains the list of source files for your application or library.

  KDE3_AUTOMOC(file1 ... fileN)

          Call this if you want to have automatic moc file handling.
          This means if you include "foo.moc" in the source file foo.cpp
          a moc file for the header foo.h will be created automatically.
          You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
          to exclude some files in the list from being processed.

  KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN )

          If you don't use the KDE3_AUTOMOC() macro, for the files
          listed here moc files will be created (named "foo.moc.cpp")

  KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h )

          Use this to generate DCOP skeletions from the listed headers.

  KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h )

           Use this to generate DCOP stubs from the listed headers.

  KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui )

          Use this to add the Qt designer ui files to your application/library.

  KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc )

          Use this to add KDE kconfig compiler files to your application/library.

  KDE3_INSTALL_LIBTOOL_FILE(target)

          This will create and install a simple libtool file for the given target.

  KDE3_ADD_EXECUTABLE(name file1 ... fileN )

          Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.

  KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )

          Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
          If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
          It creates and installs an appropriate libtool la-file.

  KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN )

          Create a KDE application in the form of a module loadable via kdeinit.
          A library named kdeinit_<name> will be created and a small executable which links to it.

  The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no longer supported.

        MPEG2_mpeg2_LIBRARY, where to find the MPEG2 library.
        MPEG2_vo_LIBRARY, where to find the vo library.

- `FindMPI`: Message Passing Interface (MPI) module.

  The Message Passing Interface (MPI) is a library used to write high-performance parallel applications that use message passing, and is typically deployed on a cluster. MPI is a standard interface (defined by the MPI forum) for which many implementations are available. All of these implementations have somewhat different compilation approaches (different include paths, libraries to link against, etc.), and this module tries to smooth out those differences.

  This module will set the following variables:

         MPI_FOUND                  TRUE if we have found MPI
         MPI_COMPILE_FLAGS          Compilation flags for MPI programs
         MPI_INCLUDE_PATH           Include path(s) for MPI header
         MPI_LINK_FLAGS             Linking flags for MPI programs
         MPI_LIBRARY                First MPI library to link against (cached)
         MPI_EXTRA_LIBRARY          Extra MPI libraries to link against (cached)
         MPI_LIBRARIES              All libraries to link MPI programs against
         MPIEXEC                    Executable for running MPI programs
         MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving it the
                                    number of processors to run on
         MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly before the
                                    executable to run.
         MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after all other flags.

  This module will attempt to auto-detect these settings, first by looking for a MPI compiler, which many MPI implementations provide as a pass-through to the native compiler to simplify the compilation of MPI programs. The MPI compiler is stored in the cache variable MPI_COMPILER, and will attempt to look for commonly-named drivers mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and recognized, it will be used to set all of the module variables. To skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the CMake cache.

  If no compiler driver is found or the compiler driver is not recognized, this module will then search for common include paths and library names to try to detect MPI.

  If CMake initially finds a different MPI than was intended, and you want to use the MPI compiler auto-detection for a different MPI implementation, set MPI_COMPILER to the MPI compiler driver you want to use (e.g., mpicxx) and then set MPI_LIBRARY to the string MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI will run again with the newly-specified MPI_COMPILER.

  When using MPIEXEC to execute MPI applications, you should typically use all of the MPIEXEC flags as follows:

         ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
           ${MPIEXEC_POSTFLAGS} ARGS

  where PROCS is the number of processors on which to execute the program, EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the MPI program.

  If you want to use just GL you can use these values

        OPENGL_gl_LIBRARY   - Path to OpenGL Library
        OPENGL_glu_LIBRARY  - Path to GLU Library

  On OSX default to using the framework version of opengl People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

- `FindOpenMP`: Finds OpenMP support

  This module can be used to detect OpenMP support in a compiler. If the compiler supports OpenMP, the flags required to compile with openmp support are set.

  This module searches for the OpenSceneGraph core "osg" library as well as OpenThreads, and whatever additional COMPONENTS (nodekits) that you specify.

          See http://www.openscenegraph.org

  NOTE: To use this module effectively you must either require CMake >= 2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and Find<etc>.cmake files into your CMAKE_MODULE_PATH.

  ==================================

  This module accepts the following variables (note mixed case)

          OpenSceneGraph_DEBUG - Enable debugging output

          OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
                                            automatically

  The following environment variables are also respected for finding the OSG and it's various components. CMAKE_PREFIX_PATH can also be used for this (see find_library() CMake documentation).

          <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
          OSG_DIR
          OSGDIR
          OSG_ROOT

  This module defines the following output variables:

          OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

          OPENSCENEGRAPH_VERSION - The version of the OSG which was found

          OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

          OPENSCENEGRAPH_LIBRARIES - The OSG libraries

  ================================== Example Usage:

        find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
            # libOpenThreads & libosg automatically searched
        include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

        add_executable(foo foo.cc)
        target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

- `FindOpenThreads`:

  OpenThreads is a C++ based threading library. Its largest userbase seems to OpenSceneGraph so you might notice I accept OSGDIR as an environment path. I consider this part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module.

  Locate OpenThreads This module defines OPENTHREADS_LIBRARY OPENTHREADS_FOUND, if false, do not try to link to OpenThreads OPENTHREADS_INCLUDE_DIR, where to find the headers

  $OPENTHREADS_DIR is an environment variable that would correspond to the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

  Created by Eric Wing.

- `FindPHP4`: Find PHP4

        PNG_INCLUDE_DIR, where to find png.h, etc.
        PNG_LIBRARIES, the libraries to link against to use PNG.
        PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
        PNG_FOUND, If false, do not try to use PNG.

  also defined, but not for general use are

        PNG_LIBRARY, where to find the PNG library.

  None of the above will be defined unles zlib can be found. PNG depends on Zlib

- `FindPackageHandleStandardArgs`:

  FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )

  This function is intended to be used in FindXXX.cmake modules files. It handles the REQUIRED, QUIET and version-related arguments to FIND_PACKAGE(). It also sets the <UPPERCASED_NAME>_FOUND variable. The package is considered found if all variables <var1>... listed contain valid results, e.g. valid filepaths.

  There are two modes of this function. The first argument in both modes is the name of the Find-module where it is called (in original casing).

  The first simple mode looks like this:

          FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

  If the variables <var1> to <varN> are all valid, then <UPPERCASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given as second argument, then the function will generate itself useful success and error messages. You can also supply a custom error message for the failure case. This is not recommended.

  The second mode is more powerful and also supports version checking:

          FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [REQUIRED_VARS <var1>...<varN>]
                                                 [VERSION_VAR   <versionvar>
                                                 [CONFIG_MODE]
                                                 [FAIL_MESSAGE "Custom failure message"] )

  As above, if <var1> through <varN> are all valid, <UPPERCASED_NAME>_FOUND will be set to TRUE. After REQUIRED_VARS the variables which are required for this package are listed. Following VERSION_VAR the name of the variable can be specified which holds the version of the package which has been found. If this is done, this version will be checked against the (potentially) specified required version used in the find_package() call. The EXACT keyword is also handled. The default messages include information about the required version and the version which has been actually found, both if the version is ok or not. Use the option CONFIG_MODE if your FindXXX.cmake module is a wrapper for a find_package(... NO_MODULE) call, in this case all the information provided by the config-mode of find_package() will be evaluated automatically. Via FAIL_MESSAGE a custom failure message can be specified, if this is not used, the default message will be displayed.

  Example for mode 1:

          FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2  DEFAULT_MSG  LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

  LibXml2 is considered to be found, if both LIBXML2_LIBRARY and LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE. If it is not found and REQUIRED was used, it fails with FATAL_ERROR, independent whether QUIET was used or not. If it is found, success will be reported, including the content of <var1>. On repeated Cmake runs, the same message won't be printed again.

  Example for mode 2:

          FIND_PACKAGE_HANDLE_STANDARD_ARGS(BISON  REQUIRED_VARS BISON_EXECUTABLE
                                                   VERSION_VAR BISON_VERSION)

  In this case, BISON is considered to be found if the variable(s) listed after REQUIRED_VAR are all valid, i.e. BISON_EXECUTABLE in this case. Also the version of BISON will be checked by using the version contained in BISON_VERSION. Since no FAIL_MESSAGE is given, the default messages will be printed.

  Another example for mode 2:

          FIND_PACKAGE(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(Automoc4  CONFIG_MODE)

  In this case, FindAutmoc4.cmake wraps a call to FIND_PACKAGE(Automoc4 NO_MODULE) and adds an additional search directory for automoc4. The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper success/error message.

- `FindPackageMessage`:

  FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

  This macro is intended to be used in FindXXX.cmake modules files. It will print a message once for each unique find result. This is useful for telling the user where a package was found. The first argument specifies the name (XXX) of the package. The second argument specifies the message to display. The third argument lists details about the find result so that if they change the message will be displayed again. The macro also obeys the QUIET argument to the find_package command.

  Example:

        IF(X11_FOUND)
          FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
            "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
        ELSE(X11_FOUND)
         ...
        ENDIF(X11_FOUND)

- `FindPerl`: Find perl

  this module looks for Perl

        PERL_EXECUTABLE - the full path to perl
        PERL_FOUND      - If false, don't attempt to use perl.

- `FindPerlLibs`: Find Perl libraries

  This module finds if PERL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PERLLIBS_FOUND    = True if perl.h & libperl were found
        PERL_INCLUDE_PATH = path to where perl.h is found
        PERL_LIBRARY      = path to libperl
        PERL_EXECUTABLE   = full path to the perl binary

  The minimum required version of Perl can be specified using the standard syntax, e.g. FIND_PACKAGE(PerlLibs 6.0)

        The following variables are also available if needed
        (introduced after CMake 2.6.4)

        PERL_SITESEARCH    = path to the sitesearch install dir
        PERL_SITELIB       = path to the sitelib install directory
        PERL_VENDORARCH    = path to the vendor arch install directory
        PERL_VENDORLIB     = path to the vendor lib install directory
        PERL_ARCHLIB       = path to the arch lib install directory
        PERL_PRIVLIB       = path to the priv lib install directory
        PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

- `FindPhysFS`:

  Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of the library to link against PHYSFS_FOUND, if false, do not try to link to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

  $PHYSFSDIR is an environment variable that would correspond to the ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

- `FindPike`: Find Pike

  This module finds if PIKE is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PIKE_INCLUDE_PATH       = path to where program.h is found
        PIKE_EXECUTABLE         = full path to the pike binary

- `FindPkgConfig`: a pkg-config module for CMake

  Usage:

         pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
           checks for all the given modules

         pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
           checks for given modules and uses the first working one

  When the 'REQUIRED' argument was set, macros will fail with an error when module(s) could not be found

  When the 'QUIET' argument is set, no status messages will be printed.

  It sets the following variables:

         PKG_CONFIG_FOUND         ... true if pkg-config works on the system
         PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
         <PREFIX>_FOUND           ... set to 1 if module(s) exist

  For the following variables two sets of values exist; first one is the common one and has the given PREFIX. The second set contains flags which are given out when pkgconfig was called with the '--static' option.

         <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
         <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
         <XPREFIX>_LDFLAGS        ... all required linker flags
         <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
         <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
         <XPREFIX>_CFLAGS         ... all required cflags
         <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

         <XPREFIX> = <PREFIX>        for common case
         <XPREFIX> = <PREFIX>_STATIC for static linking

  There are some special variables whose prefix depends on the count of given modules. When there is only one module, <PREFIX> stays unchanged. When there are multiple modules, the prefix will be changed to <PREFIX>_<MODNAME>:

         <XPREFIX>_VERSION    ... version of the module
         <XPREFIX>_PREFIX     ... prefix-directory of the module
         <XPREFIX>_INCLUDEDIR ... include-dir of the module
         <XPREFIX>_LIBDIR     ... lib-dir of the module

         <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
         <XPREFIX> = <PREFIX>_<MODNAME>

  A <MODULE> parameter can have the following formats:

         {MODNAME}            ... matches any version
         {MODNAME}>={VERSION} ... at least version <VERSION> is required
         {MODNAME}={VERSION}  ... exactly version <VERSION> is required
         {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

  Examples

         pkg_check_modules (GLIB2   glib-2.0)

         pkg_check_modules (GLIB2   glib-2.0>=2.10)
           requires at least version 2.10 of glib2 and defines e.g.
             GLIB2_VERSION=2.10.3

         pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)
           requires both glib2 and gtk2, and defines e.g.
             FOO_glib-2.0_VERSION=2.10.3
             FOO_gtk+-2.0_VERSION=2.8.20

         pkg_check_modules (XRENDER REQUIRED xrender)
           defines e.g.:
             XRENDER_LIBRARIES=Xrender;X11
             XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

         pkg_search_module (BAR     libxml-2.0 libxml2 libxml>=2)

- `FindPostgreSQL`: --------------------------------------------------------------------------

  Find the PostgreSQL installation.

  Usage: In your CMakeLists.txt file do something like this: ... # PostgreSQL FIND_PACKAGE(PostgreSQL) ... if( PostgreSQL_FOUND )

         include_directories(${PostgreSQL_INCLUDE_DIRS})
         link_directories(${PostgreSQL_LIBRARY_DIRS})

  endif( PostgreSQL_FOUND ) ... Remember to include ${PostgreSQL_LIBRARIES} in the target_link_libraries() statement.

  In Windows, we make the assumption that, if the PostgreSQL files are installed, the default directory will be C:\Program Files\PostgreSQL.

- `FindProducer`:

  Though Producer isn't directly part of OpenSceneGraph, its primary user is OSG so I consider this part of the Findosg* suite used to find OpenSceneGraph components. You'll notice that I accept OSGDIR as an environment path.

  Each component is separate and you must opt in to each module. You must also opt into OpenGL (and OpenThreads?) as these modules won't do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

  Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND, if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where to find the headers

  $PRODUCER_DIR is an environment variable that would correspond to the ./configure --prefix=$PRODUCER_DIR used in building osg.

- `FindProtobuf`:

  Locate and configure the Google Protocol Buffers library. Defines the following variables:

         PROTOBUF_FOUND - Found the Google Protocol Buffers library
         PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
         PROTOBUF_LIBRARIES - The protobuf library

  The following cache variables are also defined:

         PROTOBUF_LIBRARY - The protobuf library
         PROTOBUF_PROTOC_LIBRARY   - The protoc library
         PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
         PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler

        ====================================================================
        Example:

         find_package(Protobuf REQUIRED)
         include_directories(${PROTOBUF_INCLUDE_DIRS})

         include_directories(${CMAKE_CURRENT_BINARY_DIR})
         PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
         add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
         target_link_libraries(bar ${PROTOBUF_LIBRARY})

  NOTE: You may need to link against pthreads, depending on the platform.

        ====================================================================

  PROTOBUF_GENERATE_CPP (public function)

         SRCS = Variable to define with autogenerated
                source files
         HDRS = Variable to define with autogenerated
                header files
         ARGN = proto files

        ====================================================================

- `FindPythonInterp`: Find python interpreter

  This module finds if Python interpreter is installed and determines where the executables are. This code sets the following variables:

        PYTHONINTERP_FOUND         - Was the Python executable found
        PYTHON_EXECUTABLE          - path to the Python interpreter
        Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for

- `FindPythonLibs`: Find python libraries

  This module finds if Python is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PYTHONLIBS_FOUND           - have the Python libs been found
        PYTHON_LIBRARIES           - path to the python library
        PYTHON_INCLUDE_PATH        - path to where Python.h is found (deprecated)
        PYTHON_INCLUDE_DIRS        - path to where Python.h is found
        PYTHON_DEBUG_LIBRARIES     - path to the debug library
        Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for

- `FindQt`: Searches for all installed versions of QT.

  This should only be used if your project can work with multiple versions of QT. If not, you should just directly use FindQt4 or FindQt3. If multiple versions of QT are found on the machine, then The user must set the option DESIRED_QT_VERSION to the version they want to use. If only one version of qt is found on the machine, then the DESIRED_QT_VERSION is set to that version and the matching FindQt3 or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module is included.

        QT_REQUIRED if this is set to TRUE then if CMake can
                    not find QT4 or QT3 an error is raised
                    and a message is sent to the user.

        DESIRED_QT_VERSION OPTION is created
        QT4_INSTALLED is set to TRUE if qt4 is found.
        QT3_INSTALLED is set to TRUE if qt3 is found.

- `FindQt3`: Locate Qt include paths and libraries

  This module defines:

        QT_INCLUDE_DIR - where to find qt.h, etc.
        QT_LIBRARIES   - the libraries to link against to use Qt.
        QT_DEFINITIONS - definitions to use when
                         compiling code that uses Qt.
        QT_FOUND       - If false, don't try to use Qt.

  If you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE

  Also defined, but not for general use are:

        QT_MOC_EXECUTABLE, where to find the moc tool.
        QT_UIC_EXECUTABLE, where to find the uic tool.
        QT_QT_LIBRARY, where to find the Qt library.
        QT_QTMAIN_LIBRARY, where to find the qtmain
         library. This is only required by Qt3 on Windows.

- `FindQt4`: Find QT 4

  This module can be used to find Qt4. The most important issue is that the Qt4 qmake is available via the system path. This qmake is then used to detect basically everything else. This module defines a number of key variables and macros. The variable QT_USE_FILE is set which is the path to a CMake file that can be included to compile Qt 4 applications and libraries. It sets up the compilation environment for include directories, preprocessor defines and populates a QT_LIBRARIES variable.

  Typical usage could be something like:

         find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED )
         include(${QT_USE_FILE})
         add_executable(myexe main.cpp)
         target_link_libraries(myexe ${QT_LIBRARIES})

  The minimum required version can be specified using the standard find_package()-syntax (see example above). For compatibility with older versions of FindQt4.cmake it is also possible to set the variable QT_MIN_VERSION to the minimum required version of Qt4 before the find_package(Qt4) command. If both are used, the version used in the find_package() command overrides the one from QT_MIN_VERSION.

  When using the components argument, QT_USE_QT* variables are automatically set for the QT_USE_FILE to pick up. If one wishes to manually set them, the available ones to set include:

                          QT_DONT_USE_QTCORE
                          QT_DONT_USE_QTGUI
                          QT_USE_QT3SUPPORT
                          QT_USE_QTASSISTANT
                          QT_USE_QAXCONTAINER
                          QT_USE_QAXSERVER
                          QT_USE_QTDESIGNER
                          QT_USE_QTMOTIF
                          QT_USE_QTMAIN
                          QT_USE_QTMULTIMEDIA
                          QT_USE_QTNETWORK
                          QT_USE_QTNSPLUGIN
                          QT_USE_QTOPENGL
                          QT_USE_QTSQL
                          QT_USE_QTXML
                          QT_USE_QTSVG
                          QT_USE_QTTEST
                          QT_USE_QTUITOOLS
                          QT_USE_QTDBUS
                          QT_USE_QTSCRIPT
                          QT_USE_QTASSISTANTCLIENT
                          QT_USE_QTHELP
                          QT_USE_QTWEBKIT
                          QT_USE_QTXMLPATTERNS
                          QT_USE_PHONON
                          QT_USE_QTSCRIPTTOOLS
                          QT_USE_QTDECLARATIVE

        QT_USE_IMPORTED_TARGETS
              If this variable is set to TRUE, FindQt4.cmake will create imported
              library targets for the various Qt libraries and set the
              library variables like QT_QTCORE_LIBRARY to point at these imported
              targets instead of the library file on disk. This provides much better
              handling of the release and debug versions of the Qt libraries and is
             also always backwards compatible, except for the case that dependencies
             of libraries are exported, these will then also list the names of the
             imported targets as dependency and not the file location on disk. This
             is much more flexible, but requires that FindQt4.cmake is executed before
             such an exported dependency file is processed.

  There are also some files that need processing by some Qt tools such as moc and uic. Listed below are macros that may be used to process those files.

        macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
              create moc code from a list of files containing Qt class with
              the Q_OBJECT declaration.  Per-direcotry preprocessor definitions
              are also added.  Options may be given to moc, such as those found
              when executing "moc -help".

        macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt designer ui files.
              Options may be given to uic, such as those found
              when executing "uic -help"

        macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt resource files.
              Options may be given to rcc, such as those found
              when executing "rcc -help"

        macro QT4_GENERATE_MOC(inputfile outputfile )
              creates a rule to run moc on infile and create outfile.
              Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
              because you need a custom filename for the moc file or something similar.

        macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
              This macro is still experimental.
              It can be used to have moc automatically handled.
              So if you have the files foo.h and foo.cpp, and in foo.h a
              a class uses the Q_OBJECT macro, moc has to run on it. If you don't
              want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
              #include "foo.moc"
              in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
              scan all listed files at cmake-time for such included moc files and if it finds
              them cause a rule to be generated to run moc at build time on the
              accompanying header file foo.h.
              If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

        macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
              create a the interface header and implementation files with the
              given basename from the given interface xml file and add it to
              the list of sources

        macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
              create the interface header and implementation files
              for all listed interface xml files
              the name will be automatically determined from the name of the xml file

        macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
              create a dbus adaptor (header and implementation file) from the xml file
              describing the interface, and add it to the list of sources. The adaptor
              forwards the calls to a parent class, defined in parentheader and named
              parentclassname. The name of the generated files will be
              <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
              If <classname> is provided, then it will be used as the classname of the
              adaptor itself.

        macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
              generate the xml interface file from the given header.
              If the optional argument interfacename is omitted, the name of the
              interface file is constructed from the basename of the header with
              the suffix .xml appended.
              Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

        macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                      ts_files ... OPTIONS ...)
              out: qm_files
              in:  directories sources ts_files
              options: flags to pass to lupdate, such as -extensions to specify
              extensions for a directory scan.
              generates commands to create .ts (vie lupdate) and .qm
              (via lrelease) - files from directories and/or sources. The ts files are
              created and/or updated in the source tree (unless given with full paths).
              The qm files are generated in the build tree.
              Updating the translations can be done by adding the qm_files
              to the source list of your library/executable, so they are
              always updated, or by adding a custom target to control when
              they get updated/generated.

        macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
              out: qm_files
              in:  ts_files
              generates commands to create .qm from .ts - files. The generated
              filenames can be found in qm_files. The ts_files
              must exists and are not updated in any way.

        Below is a detailed list of variables that FindQt4.cmake sets.
        QT_FOUND         If false, don't try to use Qt.

        QT_QTDECLARATIVE_FOUND   True if QtDeclarative was found.

        QT_MAC_USE_COCOA    For Mac OS X, its whether Cocoa or Carbon is used.
                            In general, this should not be used, but its useful
                            when having platform specific code.

        QT_DEFINITIONS   Definitions to use when compiling code that uses Qt.
                         You do not need to use this if you include QT_USE_FILE.
                         The QT_USE_FILE will also define QT_DEBUG and QT_NO_DEBUG
                         to fit your current build type.  Those are not contained
                         in QT_DEFINITIONS.

        QT_INCLUDES      List of paths to all include directories of
                         Qt4 QT_INCLUDE_DIR and QT_QTCORE_INCLUDE_DIR are
                         always in this variable even if NOTFOUND,
                         all other INCLUDE_DIRS are
                         only added if they are found.
                         You do not need to use this if you include QT_USE_FILE.

        Include directories for the Qt modules are listed here.

  These are around for backwards compatibility they will be set

        QT_WRAP_CPP  Set true if QT_MOC_EXECUTABLE is found
        QT_WRAP_UI   Set true if QT_UIC_EXECUTABLE is found

  These variables do _NOT_ have any effect anymore (compared to FindQt.cmake)

        QT_MT_REQUIRED         Qt4 is now always multithreaded

  These variables are set to "" Because Qt structure changed (They make no sense in Qt4)

        QT_QT_LIBRARY        Qt-Library is now split

- `FindQuickTime`:

  Locate QuickTime This module defines QUICKTIME_LIBRARY QUICKTIME_FOUND, if false, do not try to link to gdal QUICKTIME_INCLUDE_DIR, where to find the headers

  $QUICKTIME_DIR is an environment variable that would correspond to the ./configure --prefix=$QUICKTIME_DIR

  Created by Eric Wing.

- `FindRTI`: Try to find M&S HLA RTI libraries

  This module finds if any HLA RTI is installed and locates the standard RTI include files and libraries.

  RTI is a simulation infrastructure standardized by IEEE and SISO. It has a well defined C++ API that assures that simulation applications are independent on a particular RTI implementation.

        http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

  This code sets the following variables:

        RTI_INCLUDE_DIR = the directory where RTI includes file are found
        RTI_LIBRARIES = The libraries to link against to use RTI
        RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
        RTI_FOUND = Set to FALSE if any HLA RTI was not found

  Report problems to <certi-devel@nongnu.org>

- `FindRuby`: Find Ruby

  This module finds if Ruby is installed and determines where the include files and libraries are. Ruby 1.8 and 1.9 are supported.

  The minimum required version of Ruby can be specified using the standard syntax, e.g. FIND_PACKAGE(Ruby 1.8)

  It also determines what the name of the library is. This code sets the following variables:

        RUBY_EXECUTABLE   = full path to the ruby binary
        RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
        RUBY_LIBRARY      = full path to the ruby library
        RUBY_VERSION      = the version of ruby which was found, e.g. "1.8.7"
        RUBY_FOUND        = set to true if ruby ws found successfully

        RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it

- `FindSDL`:

  Locate SDL library This module defines SDL_LIBRARY, the name of the library to link against SDL_FOUND, if false, do not try to link to SDL SDL_INCLUDE_DIR, where to find SDL.h

  This module responds to the the flag: SDL_BUILDING_LIBRARY If this is defined, then no SDL_main will be linked in because only applications need main(). Otherwise, it is assumed you are building an application and this module will attempt to locate and set the the proper link flags as part of the returned SDL_LIBRARY variable.

  Don't forget to include SDLmain.h and SDLmain.m your project for the OS X framework based version. (Other versions link to -lSDLmain which this module will try to find on your behalf.) Also for OS X, this module will automatically add the -framework Cocoa on your behalf.

  Additional Note: If you see an empty SDL_LIBRARY_TEMP in your configuration and no SDL_LIBRARY, it means CMake did not find your SDL library (SDL.dll, libsdl.so, SDL.framework, etc). Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again. Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this value as appropriate. These values are used to generate the final SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY does not get created.

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL. l.e.galup 9-20-02

  Modified by Eric Wing. Added code to assist with automated building by using environmental variables and providing a more controlled/consistent search behavior. Added new modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). Also corrected the header search path to follow "proper" SDL guidelines. Added a search for SDLmain which is needed by some platforms. Added a search for threads which is needed by some platforms. Added needed compile switches for MinGW.

  On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selection or set the CMake environment CMAKE_INCLUDE_PATH to modify the search paths.

  Note that the header path has changed from SDL/SDL.h to just SDL.h This needed to change because "proper" SDL convention is #include "SDL.h", not <SDL/SDL.h>. This is done for portability reasons because not all systems place things in SDL/ (see FreeBSD).

- `FindSDL_image`:

  Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the name of the library to link against SDLIMAGE_FOUND, if false, do not try to link to SDL SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

  Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

- `FindSDL_mixer`:

  Locate SDL_mixer library This module defines SDLMIXER_LIBRARY, the name of the library to link against SDLMIXER_FOUND, if false, do not try to link to SDL SDLMIXER_INCLUDE_DIR, where to find SDL/SDL.h

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

  Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

- `FindSDL_net`:

  Locate SDL_net library This module defines SDLNET_LIBRARY, the name of the library to link against SDLNET_FOUND, if false, do not try to link against SDLNET_INCLUDE_DIR, where to find the headers

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

  Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

- `FindSDL_sound`:

  Locates the SDL_sound library

- `FindSDL_ttf`:

  Locate SDL_ttf library This module defines SDLTTF_LIBRARY, the name of the library to link against SDLTTF_FOUND, if false, do not try to link to SDL SDLTTF_INCLUDE_DIR, where to find SDL/SDL.h

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

  Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

- `FindSWIG`: Find SWIG

  This module finds an installed SWIG. It sets the following variables:

        SWIG_FOUND - set to true if SWIG is found
        SWIG_DIR - the directory where swig is installed
        SWIG_EXECUTABLE - the path to the swig executable
        SWIG_VERSION   - the version number of the swig executable

  The minimum required version of SWIG can be specified using the standard syntax, e.g. FIND_PACKAGE(SWIG 1.1)

  All information is collected from the SWIG_EXECUTABLE so the version to be found can be changed from the command line by means of setting SWIG_EXECUTABLE

- `FindSelfPackers`: Find upx

  This module looks for some executable packers (i.e. softwares that compress executables or shared libs into on-the-fly self-extracting executables or shared libs. Examples:

        UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

- `FindSquish`: -- Typical Use

  This module can be used to find Squish (currently support is aimed at version 3).

        SQUISH_FOUND                    If false, don't try to use Squish

        SQUISH_INSTALL_DIR              The Squish installation directory (containing bin, lib, etc)
        SQUISH_SERVER_EXECUTABLE        The squishserver executable
        SQUISH_CLIENT_EXECUTABLE        The squishrunner executable

        SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
        SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
        SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?

  macro SQUISH_ADD_TEST(testName applicationUnderTest testSuite testCase)

        ENABLE_TESTING()
        FIND_PACKAGE(Squish)
        IF (SQUISH_FOUND)
          SQUISH_ADD_TEST(myTestName myApplication testSuiteName testCaseName)
        ENDIF (SQUISH_FOUND)

- `FindSubversion`: Extract information from a subversion working copy

  The module defines the following variables:

        Subversion_SVN_EXECUTABLE - path to svn command line client
        Subversion_VERSION_SVN - version of svn command line client
        Subversion_FOUND - true if the command line client was found
        SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

  The minimum required version of Subversion can be specified using the standard syntax, e.g. FIND_PACKAGE(Subversion 1.4)

  If the command line client executable is found two macros are defined:

        Subversion_WC_INFO(<dir> <var-prefix>)
        Subversion_WC_LOG(<dir> <var-prefix>)

  Subversion_WC_INFO extracts information of a subversion working copy at a given location. This macro defines the following variables:

        <var-prefix>_WC_URL - url of the repository (at <dir>)
        <var-prefix>_WC_ROOT - root url of the repository
        <var-prefix>_WC_REVISION - current revision
        <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
        <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
        <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
        <var-prefix>_WC_INFO - output of command `svn info <dir>'

  Subversion_WC_LOG retrieves the log message of the base revision of a subversion working copy at a given location. This macro defines the variable:

        <var-prefix>_LAST_CHANGED_LOG - last log of base revision

  Example usage:

        FIND_PACKAGE(Subversion)
        IF(SUBVERSION_FOUND)
          Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
          MESSAGE("Current revision is ${Project_WC_REVISION}")
          Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
          MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
        ENDIF(SUBVERSION_FOUND)

- `FindTCL`: TK_INTERNAL_PATH was removed.

  This module finds if Tcl is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        TCL_FOUND              = Tcl was found
        TK_FOUND               = Tk was found
        TCLTK_FOUND            = Tcl and Tk were found
        TCL_LIBRARY            = path to Tcl library (tcl tcl80)
        TCL_INCLUDE_PATH       = path to where tcl.h can be found
        TCL_TCLSH              = path to tclsh binary (tcl tcl80)
        TK_LIBRARY             = path to Tk library (tk tk80 etc)
        TK_INCLUDE_PATH        = path to where tk.h can be found
        TK_WISH                = full path to the wish executable

  In an effort to remove some clutter and clear up some issues for people who are not necessarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are:

         => they were only useful for people writing Tcl/Tk extensions.
         => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs
            are created and there is no real reason to pick a single one
            specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
            Let's leave that choice to the user by allowing him to assign
            TCL_LIBRARY to any Tcl library, debug or not.
         => this ended up being only a Win32 variable, and there is a lot of
            confusion regarding the location of this file in an installed Tcl/Tk
            tree anyway (see 8.5 for example). If you need the internal path at
            this point it is safer you ask directly where the *source* tree is
            and dig from there.

- `FindTIFF`: Find TIFF library

  Find the native TIFF includes and library This module defines

        TIFF_INCLUDE_DIR, where to find tiff.h, etc.
        TIFF_LIBRARIES, libraries to link against to use TIFF.
        TIFF_FOUND, If false, do not try to use TIFF.

  also defined, but not for general use are

        TIFF_LIBRARY, where to find the TIFF library.

- `FindTclStub`: TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

  This module finds Tcl stub libraries. It first finds Tcl include files and libraries by calling FindTCL.cmake. How to Use the Tcl Stubs Library:

         http://tcl.activestate.com/doc/howto/stubs.html

  Using Stub Libraries:

         http://safari.oreilly.com/0130385603/ch48lev1sec3

  This code sets the following variables:

        TCL_STUB_LIBRARY       = path to Tcl stub library
        TK_STUB_LIBRARY        = path to Tk stub library
        TTK_STUB_LIBRARY       = path to ttk stub library

  In an effort to remove some clutter and clear up some issues for people who are not necessarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are:

         => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs
            are created and there is no real reason to pick a single one
            specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
            Let's leave that choice to the user by allowing him to assign
            TCL_STUB_LIBRARY to any Tcl library, debug or not.

- `FindTclsh`: Find tclsh

  This module finds if TCL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        TCLSH_FOUND = TRUE if tclsh has been found
        TCL_TCLSH = the path to the tclsh executable

  In cygwin, look for the cygwin version first. Don't look for it later to avoid finding the cygwin version on a Win32 build.

- `FindThreads`: This module determines the thread library of the system.

  The following variables are set

        CMAKE_THREAD_LIBS_INIT     - the thread library
        CMAKE_USE_SPROC_INIT       - are we using sproc?
        CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
        CMAKE_USE_PTHREADS_INIT    - are we using pthreads
        CMAKE_HP_PTHREADS_INIT     - are we using hp pthreads

  For systems with multiple thread libraries, caller can set

        CMAKE_THREAD_PREFER_PTHREAD

- `FindUnixCommands`: Find unix commands from cygwin

  This module looks for some usual Unix commands.

- `FindVTK`: Find a VTK installation or build tree.

  The following variables are set if VTK is found. If VTK is not found, VTK_FOUND is set to false.

        VTK_FOUND         - Set to true when VTK is found.

- `Findosg`:

  NOTE: It is highly recommended that you use the new FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this Find module directly.

  This is part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. You must also opt into OpenGL and OpenThreads (and Producer if needed) as these modules won't do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

- `Findosg_functions`:

  This CMake file contains two macros to assist with searching for OSG libraries and nodekits.

- `FindwxWidgets`: Find a wxWidgets (a.k.a., wxWindows) installation.

  This module finds if wxWidgets is installed and selects a default configuration to use. wxWidgets is a modular library. To specify the modules that you will use, you need to name them as components to the package:

  FIND_PACKAGE(wxWidgets COMPONENTS core base ...)

  There are two search branches: a windows style and a unix style. For windows, the following variables are searched for and set to defaults in case of multiple choices. Change them if the defaults are not desired (i.e., these are the only variables you should change to select a configuration):

        wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                  (e.g., C:/wxWidgets-2.6.3).
        wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                  (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
        wxWidgets_CONFIGURATION - Configuration to use
                                  (e.g., msw, mswd, mswu, mswunivud, etc.)
        wxWidgets_EXCLUDE_COMMON_LIBRARIES
                                - Set to TRUE to exclude linking of
                                  commonly required libs (e.g., png tiff
                                  jpeg zlib regex expat).

  For unix style it uses the wx-config utility. You can select between debug/release, unicode/ansi, universal/non-universal, and static/shared in the QtDialog or ccmake interfaces by turning ON/OFF the following variables:

        wxWidgets_USE_DEBUG
        wxWidgets_USE_UNICODE
        wxWidgets_USE_UNIVERSAL
        wxWidgets_USE_STATIC

  There is also a wxWidgets_CONFIG_OPTIONS variable for all other options that need to be passed to the wx-config utility. For example, to use the base toolkit found in the /usr/local path, set the variable (before calling the FIND_PACKAGE command) as such:

        SET(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

  The following are set after the configuration is done for both windows and unix style:

        wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
        wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                     i.e., where to find "wx/wx.h" and
                                     "wx/setup.h"; possibly empty for unices.
        wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
        wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                     rpath on UNIX. Typically an empty string
                                     in WIN32 environment.
        wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                     against WX, e.g. WXUSINGDLL
        wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
                                     against WX debug builds, e.g. __WXDEBUG__
        wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
                                     unices, empty on WIN32. Essentially
                                     "`wx-config --cxxflags`".
        wxWidgets_USE_FILE         - Convenience include file.

  Sample usage:

         # Note that for MinGW users the order of libs is important!
         FIND_PACKAGE(wxWidgets COMPONENTS net gl core base)
         IF(wxWidgets_FOUND)
           INCLUDE(${wxWidgets_USE_FILE})
           # and for each of your dependent executable/library targets:
           TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
         ENDIF(wxWidgets_FOUND)

  If wxWidgets is required (i.e., not an optional part):

         FIND_PACKAGE(wxWidgets REQUIRED net gl core base)
         INCLUDE(${wxWidgets_USE_FILE})
         # and for each of your dependent executable/library targets:
         TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})

- `FindwxWindows`: Find wxWindows (wxWidgets) installation

  This module finds if wxWindows/wxWidgets is installed and determines where the include files and libraries are. It also determines what the name of the library is. Please note this file is DEPRECATED and replaced by FindwxWidgets.cmake. This code sets the following variables:

        WXWINDOWS_FOUND     = system has WxWindows
        WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                              on Unix/Linux with additional
                              linker flags from
                              "wx-config --libs"
        CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                     essentially "`wx-config --cxxflags`"
                                     on Linux
        WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
        WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                      Unix
        WXWINDOWS_DEFINITIONS      = extra defines

  OPTIONS If you need OpenGL support please

        SET(WXWINDOWS_USE_GL 1)

  in your CMakeLists.txt *before* you include this file.

        HAVE_ISYSTEM      - true required to replace -I by -isystem on g++

  For convenience include Use_wxWindows.cmake in your project's CMakeLists.txt using INCLUDE(Use_wxWindows).

  USAGE

        SET(WXWINDOWS_USE_GL 1)
        FIND_PACKAGE(wxWindows)

  NOTES wxWidgets 2.6.x is supported for monolithic builds e.g. compiled in wx/build/msw dir as:

- `FortranCInterface`: Fortran/C Interface Detection

  This module automatically detects the API by which C and Fortran languages interact. Variables indicate if the mangling is found:

         FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
         FortranCInterface_MODULE_FOUND = Module subroutines and functions
                                          (declared by "MODULE PROCEDURE")

  A function is provided to generate a C header file containing macros to mangle symbol names:

         FortranCInterface_HEADER(<file>
                                  [MACRO_NAMESPACE <macro-ns>]
                                  [SYMBOL_NAMESPACE <ns>]
                                  [SYMBOLS [<module>:]<function> ...])

  It generates in <file> definitions of the following macros:

         #define FortranCInterface_GLOBAL (name,NAME) ...
         #define FortranCInterface_GLOBAL_(name,NAME) ...
         #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
         #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

  These macros mangle four categories of Fortran symbols, respectively:

         - Global symbols without '_': call mysub()
         - Global symbols with '_'   : call my_sub()
         - Module symbols without '_': use mymod; call mysub()
         - Module symbols with '_'   : use mymod; call my_sub()

  If mangling for a category is not known, its macro is left undefined. All macros require raw names in both lower case and upper case. The MACRO_NAMESPACE option replaces the default "FortranCInterface_" prefix with a given namespace "<macro-ns>".

  The SYMBOLS option lists symbols to mangle automatically with C preprocessor definitions:

         <function>          ==> #define <ns><function> ...
         <module>:<function> ==> #define <ns><module>_<function> ...

  If the mangling for some symbol is not known then no preprocessor definition is created, and a warning is displayed. The SYMBOL_NAMESPACE option prefixes all preprocessor definitions generated by the SYMBOLS option with a given namespace "<ns>".

  Example usage:

         include(FortranCInterface)
         FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

  This creates a "FC.h" header that defines mangling macros FC_GLOBAL(), FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().

  Example usage:

         include(FortranCInterface)
         FortranCInterface_HEADER(FCMangle.h
                                  MACRO_NAMESPACE "FC_"
                                  SYMBOL_NAMESPACE "FC_"
                                  SYMBOLS mysub mymod:my_sub)

  This creates a "FCMangle.h" header that defines the same FC_*() mangling macros as the previous example plus preprocessor symbols FC_mysub and FC_mymod_my_sub.

  Another function is provided to verify that the Fortran and C/C++ compilers work together:

         FortranCInterface_VERIFY([CXX] [QUIET])

  It tests whether a simple test executable using Fortran and C (and C++ when the CXX option is given) compiles and links successfully. The result is stored in the cache entry FortranCInterface_VERIFIED_C (or FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean. If the check fails and QUIET is not given the function terminates with a FATAL_ERROR message describing the problem. The purpose of this check is to stop a build early for incompatible compiler combinations.

  FortranCInterface is aware of possible GLOBAL and MODULE manglings for many Fortran compilers, but it also provides an interface to specify new possible manglings. Set the variables

         FortranCInterface_GLOBAL_SYMBOLS
         FortranCInterface_MODULE_SYMBOLS

  before including FortranCInterface to specify manglings of the symbols "MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub". For example, the code:

         set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
           #                                  ^^^^^  ^^^^^^   ^^^^^
         set(FortranCInterface_MODULE_SYMBOLS
             __mymodule_MOD_mysub __my_module_MOD_my_sub)
           #   ^^^^^^^^     ^^^^^   ^^^^^^^^^     ^^^^^^
         include(FortranCInterface)

  tells FortranCInterface to try given GLOBAL and MODULE manglings. (The carets point at raw symbol names for clarity in this example but are not needed.)

- `GetPrerequisites`: Functions to analyze and list executable file prerequisites.

  This module provides functions to list the .dll, .dylib or .so files that an executable or shared library file depends on. (Its prerequisites.)

  It uses various tools to obtain the list of required shared library files:

         dumpbin (Windows)
         ldd (Linux/Unix)
         otool (Mac OSX)

  The following functions are provided by this module:

         get_prerequisites
         list_prerequisites
         list_prerequisites_by_glob
         gp_append_unique
         is_file_executable
         gp_item_default_embedded_path
           (projects can override with gp_item_default_embedded_path_override)
         gp_resolve_item
           (projects can override with gp_resolve_item_override)
         gp_resolved_file_type
           (projects can override with gp_resolved_file_type_override)
         gp_file_type

  Requires CMake 2.6 or greater because it uses function, break, return and PARENT_SCOPE.

        GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
                          <dirs>)

  Get the list of shared library files required by <target>. The list in the variable named <prerequisites_var> should be empty on first entry to this function. On exit, <prerequisites_var> will contain the list of required shared library files.

  <target> is the full path to an executable file. <prerequisites_var> is the name of a CMake variable to contain the results. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. If <recurse> is set to 1 all prerequisites will be found recursively, if set to 0 only direct prerequisites are listed. <exepath> is the path to the top level executable used for @executable_path replacment on the Mac. <dirs> is a list of paths where libraries might be found: these paths are searched first when a target without any path info is given. Then standard system locations are also searched: PATH, Framework locations, /usr/lib...

        LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

  Print a message listing the prerequisites of <target>.

  <target> is the name of a shared library or executable target or the full path to a shared library or executable file. If <recurse> is set to 1 all prerequisites will be found recursively, if set to 0 only direct prerequisites are listed. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. With <verbose> set to 0 only the full path names of the prerequisites are printed, set to 1 extra informatin will be displayed.

        LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

  Print the prerequisites of shared library and executable files matching a globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is a globbing expression used with "file(GLOB" or "file(GLOB_RECURSE" to retrieve a list of matching files. If a matching file is executable, its prerequisites are listed.

  Any additional (optional) arguments provided are passed along as the optional arguments to the list_prerequisites calls.

        GP_APPEND_UNIQUE(<list_var> <value>)

  Append <value> to the list variable <list_var> only if the value is not already in the list.

        IS_FILE_EXECUTABLE(<file> <result_var>)

  Return 1 in <result_var> if <file> is a binary executable, 0 otherwise.

        GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

  Return the path that others should refer to the item by when the item is embedded inside a bundle.

  Override on a per-project basis by providing a project-specific gp_item_default_embedded_path_override function.

        GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)

  Resolve an item into an existing full path file.

  Override on a per-project basis by providing a project-specific gp_resolve_item_override function.

        GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)

  Return the type of <file> with respect to <original_file>. String describing type of prerequisite is returned in variable named <type_var>.

  Use <exepath> and <dirs> if necessary to resolve non-absolute <file> values -- but only for non-embedded items.

  Possible types are:

         system
         local
         embedded
         other

  Override on a per-project basis by providing a project-specific gp_resolved_file_type_override function.

        GP_FILE_TYPE(<original_file> <file> <type_var>)

  Return the type of <file> with respect to <original_file>. String describing type of prerequisite is returned in variable named <type_var>.

  Possible types are:

         system
         local
         embedded
         other

- `InstallRequiredSystemLibraries`:

  By including this file, all library files listed in the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS will be installed with INSTALL(PROGRAMS ...) into bin for WIN32 and lib for non-WIN32. If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE before including this file, then the INSTALL command is not called. The user can use the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and install them however they want. If it is the MSVC compiler, then the microsoft run time libraries will be found and automatically added to the CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS, and installed. If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC compiler, then the debug libraries are installed when available. If CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY is set then only the debug libraries are installed when both debug and release are available. If CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are installed as well as the CRT run time libraries. If CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION is set then the libraries are installed to that directory rather than the default. If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is NOT set, then this file warns about required files that do not exist. You can set this variable to ON before including this file to avoid the warning. For example, the Visual Studio Express editions do not include the redistributable files, so if you include this file on a machine with only VS Express installed, you'll get the warning.

- `MacroAddFileDependencies`: MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

  Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged. There are usually better ways to specify the correct dependencies.

  MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a convenience wrapper around the OBJECT_DEPENDS source file property. You can just use SET_PROPERTY(SOURCE <file> APPEND PROPERTY OBJECT_DEPENDS depend_files) instead.

- `Qt4ConfigDependentSettings`:

  This file is included by FindQt4.cmake, don't include it directly.

- `Qt4Macros`:

  This file is included by FindQt4.cmake, don't include it directly.

- `SelectLibraryConfigurations`:

  select_library_configurations( basename )

  This macro takes a library base name as an argument, and will choose good values for basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what has been found and set. If only basename_LIBRARY_RELEASE is defined, basename_LIBRARY, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE will be set to the release value. If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY, basename_LIBRARY_DEBUG and basename_LIBRARY_RELEASE will take the debug value.

  If the generator supports configuration types, then basename_LIBRARY and basename_LIBRARIES will be set with debug and optimized flags specifying the library to be used for the given configuration. If no build type has been set or the generator in use does not support configuration types, then basename_LIBRARY and basename_LIBRARIES will take only the release values.

- `SquishTestScript`:

  This script launches a GUI test using Squish. You should not call the script directly; instead, you should access it via the SQUISH_ADD_TEST macro that is defined in FindSquish.cmake.

  This script starts the Squish server, launches the test on the client, and finally stops the squish server. If any of these steps fail (including if the tests do not pass) then a fatal error is raised.

- `TestBigEndian`: Define macro to determine endian type

  Check if the system is big endian or little endian

        TEST_BIG_ENDIAN(VARIABLE)
        VARIABLE - variable to store the result to

- `TestCXXAcceptsFlag`: Test CXX compiler for a flag

  Check if the CXX compiler accepts a flag

        Macro CHECK_CXX_ACCEPTS_FLAG(FLAGS VARIABLE) -
           checks if the function exists
        FLAGS - the flags to try
        VARIABLE - variable to store the result

- `TestForANSIForScope`: Check for ANSI for scope support

  Check if the compiler restricts the scope of variables declared in a for-init-statement to the loop body.

        CMAKE_NO_ANSI_FOR_SCOPE - holds result

- `TestForANSIStreamHeaders`: Test for compiler support of ANSI stream headers iostream, etc.

  check if the compiler supports the standard ANSI iostream header (without the .h)

        CMAKE_NO_ANSI_STREAM_HEADERS - defined by the results

- `TestForSSTREAM`: Test for compiler support of ANSI sstream header

  check if the compiler supports the standard ANSI sstream header

        CMAKE_NO_ANSI_STRING_STREAM - defined by the results

- `TestForSTDNamespace`: Test for std:: namespace support

  check if the compiler supports std:: on stl classes

        CMAKE_NO_STD_NAMESPACE - defined by the results

- `UseEcos`: This module defines variables and macros required to build eCos application.

  This file contains the following macros: ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos executable ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts the path of the source files and puts the result into VAR

  Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable the ARM ELF toolchain for the directory where it is called ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the PowerPC toolchain for the directory where it is called

  It contains the following variables: ECOS_DEFINITIONS ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable for internal use only:

        ECOS_ADD_TARGET_LIB

- `UsePkgConfig`: obsolete pkg-config module for CMake

  Defines the following macros:

  PKGCONFIG(package includedir libdir linkflags cflags)

  Calling PKGCONFIG will fill the desired information into the 4 given arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT found or the specified software package doesn't exist, the variable will be empty when the function returns, otherwise they will contain the respective information

- `UseQt4`: Use Module for QT4

  Sets up C and C++ to use Qt 4. It is assumed that FindQt.cmake has already been loaded. See FindQt.cmake for information on how to load Qt 4 into your CMake project.

- `UseSWIG`: SWIG module for CMake

  Defines the following macros:

         SWIG_ADD_MODULE(name language [ files ])
           - Define swig module with given name and specified language
         SWIG_LINK_LIBRARIES(name [ libraries ])
           - Link libraries to swig module

  All other macros are for internal use only. To get the actual name of the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}. Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add special flags to all swig calls. Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the swig generated module (swig -outdir option) The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra dependencies for the generated modules. If the source file generated by swig need some special flag you can use SET_SOURCE_FILES_PROPERTIES( ${swig_generated_file_fullname}

              PROPERTIES COMPILE_FLAGS "-bla")

- `Use_wxWindows`: ---------------------------------------------------

  This convenience include finds if wxWindows is installed and set the appropriate libs, incdirs, flags etc. author Jan Woetzel <jw -at- mip.informatik.uni-kiel.de> (07/2003)

  USAGE:

         just include Use_wxWindows.cmake
         in your projects CMakeLists.txt

  INCLUDE( ${CMAKE_MODULE_PATH}/Use_wxWindows.cmake)

         if you are sure you need GL then

  SET(WXWINDOWS_USE_GL 1)

         *before* you include this file.

- `UsewxWidgets`: Convenience include for using wxWidgets library.

  Determines if wxWidgets was FOUND and sets the appropriate libs, incdirs, flags, etc. INCLUDE_DIRECTORIES and LINK_DIRECTORIES are called.

  USAGE

        # Note that for MinGW users the order of libs is important!
        FIND_PACKAGE(wxWidgets REQUIRED net gl core base)
        INCLUDE(${wxWidgets_USE_FILE})
        # and for each of your dependant executable/library targets:
        TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})

  DEPRECATED

        LINK_LIBRARIES is not called in favor of adding dependencies per target.
