"Finds and loads settings from an external project. <package>_FOUND "
"will be set to indicate whether the package was found. Settings that "
"can be used when <package>_FOUND is true are package-specific. "
"A package-specific list of components may be listed after the "
"REQUIRED option, or after the COMPONENTS option if no REQUIRED "
"option is given. The \"major.minor\" version argument is currently "
"a placeholder for future use and is ignored. "
"The command has two modes by which it searches for packages: "
"\"Module\" mode and \"Config\" mode."
"\n"
"Module mode has a reduced signature:\n"
" find_package(<package> [major.minor] [QUIET]\n"
" [[REQUIRED|COMPONENTS] [components...]])\n"
"CMake searches for a file called \"Find<package>.cmake\" in "
"the CMAKE_MODULE_PATH followed by the CMake installation. "
"If the file is found, it is read and processed by CMake. "
"It is responsible for finding the package "
"or producing an error message if package content cannot be found. "
"Otherwise the command proceeds to Config mode. The NO_MODULE "
"option may be used to skip Module mode explicitly, but the option "
"is implied by use of options not specified in the reduced signature."
"\n"
"Config mode attempts to locate a configuration file provided by the "
"package to be found. A cache entry called <package>_DIR is created to "
"hold the directory containing the file. "
"By default the command searches for a package with the name <package>. "
"If the NAMES option is given the names following it are used instead "
"of <package>. "
"The command searches for a file called \"<name>Config.cmake\" or "
"\"<lower-case-name>-config.cmake\" for each name specified. "
"A replacement set of possible configuration file names may be given "
"using the CONFIGS option. "
"The search procedure is specified below. Once found, the configuration "
"file is read and processed by CMake. Since the file is provided by the "
"package it already knows the location of package contents. "
"The full path to the configuration file is stored in the cmake "
"variable <package>_CONFIG."
"\n"
"If the package configuration file cannot be found CMake "
"will generate an error describing the problem unless the QUIET "
"argument is specified. If REQUIRED is specified and the package "
"is not found a fatal error is generated and the configure step stops "
"executing. If <package>_DIR has been set to a directory not containing "
"a configuration file a fatal error is always generated because user "
"intervention is required."
"\n"
"Config mode provides an elaborate interface and search procedure. "
"Much of the interface is provided for completeness and for use "
"internally by find-modules loaded by Module mode. "
"Most user code should simply call\n"
" find_package(<package> [REQUIRED|QUIET])\n"
"in order to find a package. Package maintainers providing CMake "
"package configuration files are encouraged to name and install "
"them such that the procedure outlined below will find them "
"without requiring use of additional options."
"\n"
"CMake constructs a set of possible installation prefixes for the "
"package. Under each prefix several directories are searched for a "
"configuration file. The tables below show the directories searched. "
"Each entry is meant for installation trees following Windows (W), "
"UNIX (U), or Apple (A) conventions.\n"
" <prefix>/ (W)\n"
" <prefix>/(cmake|CMake)/ (W)\n"
" <prefix>/(share|lib)/<name>*/ (U)\n"
" <prefix>/(share|lib)/<name>*/(cmake|CMake)/ (U)\n"
"On systems supporting OS X Frameworks and Application Bundles "
"the following directories are searched for frameworks or bundles "
"containing a configuration file:\n"
" <prefix>/<name>.framework/Resources/ (A)\n"
" <prefix>/<name>.framework/Resources/CMake/ (A)\n"
" <prefix>/<name>.framework/Versions/*/Resources/ (A)\n"
" <prefix>/<name>.framework/Versions/*/Resources/CMake/ (A)\n"
" <prefix>/<name>.app/Contents/Resources/ (A)\n"
" <prefix>/<name>.app/Contents/Resources/CMake/ (A)\n"
"In all cases the <name> is treated as case-insensitive and corresponds "
"to any of the names specified (<package> or names given by NAMES). "
"If PATH_SUFFIXES is specified the suffixes are appended to each "
"(W) or (U) directory entry one-by-one.\n"
"This set of directories is intended to work in cooperation with "
"projects that provide configuration files in their installation trees. "
"Directories above marked with (W) are intended for installations on "
"Windows where the prefix may point at the top of an application's "
"installation directory. Those marked with (U) are intended for "
"installations on UNIX platforms where the prefix is shared by "
"multiple packages. This is merely a convention, so all (W) and (U) "
"directories are still searched on all platforms. "
"Directories marked with (A) are intended for installations on "
"Apple platforms. The cmake variables CMAKE_FIND_FRAMEWORK and "
"CMAKE_FIND_APPBUNDLE determine the order of preference "
"as specified below.\n"
"The set of installation prefixes is constructed using the following "
"steps. If NO_DEFAULT_PATH is specified steps 1-5 are skipped.\n"
"1. Search cmake specific environment variables. This "
"can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.\n"
" CMAKE_PREFIX_PATH\n"
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
"2. Search cmake variables with the same names as the cmake specific "
"environment variables. These are intended to be used on the command "
"line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH "
"is passed.\n"
" CMAKE_PREFIX_PATH\n"
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
"3. Search the standard system environment variables. "
"This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed. "
"Path entries ending in \"/bin\" or \"/sbin\" are automatically "
"converted to their parent directories.\n"
" PATH\n"
"4. Search project build trees recently configured in a CMake GUI. "
"This can be skipped if NO_CMAKE_BUILDS_PATH is passed. "
"It is intended for the case when a user is building multiple "
"dependent projects one after another.\n"
"5. Search cmake variables defined in the Platform files "
"for the current system. This can be skipped if NO_CMAKE_SYSTEM_PATH "
"is passed.\n"
" CMAKE_SYSTEM_PREFIX_PATH\n"
" CMAKE_SYSTEM_FRAMEWORK_PATH\n"
" CMAKE_SYSTEM_APPBUNDLE_PATH\n"
"6. Search paths specified by the PATHS option.\n"
