"Finds and loads settings from an external project. "
"<package>_FOUND will be set to indicate whether the package was found. "
"When the package is found package-specific information is provided "
"through variables documented by the package itself. "
"The QUIET option disables messages if the package cannot be found. "
"The REQUIRED option stops processing with an error message if the "
"package cannot be found. "
"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 [version] argument requests a version with which the package found "
"should be compatible (format is major[.minor[.patch[.tweak]]]). "
"The EXACT option requests that the version be matched exactly. "
"If no [version] and/or component list is given to a recursive "
"invocation inside a find-module, the corresponding arguments "
"are forwarded automatically from the outer call (including the "
"EXACT flag for [version]). "
"Version support is currently provided only on a package-by-package "
"basis (details below).\n"
"User code should generally look for packages using the above simple "
"signature. The remainder of this command documentation specifies the "
"full command signature and details of the search process. Project "
"maintainers wishing to provide a package to be found by this command "
"are encouraged to read on.\n"
"The command has two modes by which it searches for packages: "
"\"Module\" mode and \"Config\" mode. "
"Module mode is available when the command is invoked with the above "
"reduced signature. "
"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, checking the version, "
"and producing any needed messages. "
"Many find-modules provide limited or no support for versioning; "
"check the module documentation. "
"If no module is found the command proceeds to Config mode.\n"
"The complete Config mode command signature is:\n"
" find_package(<package> [version] [EXACT] [QUIET]\n"
" [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]\n"
" [NO_POLICY_SCOPE]\n"
" [NAMES name1 [name2 ...]]\n"
" [CONFIGS config1 [config2 ...]]\n"
" [HINTS path1 [path2 ... ]]\n"
" [PATHS path1 [path2 ... ]]\n"
" [PATH_SUFFIXES suffix1 [suffix2 ...]]\n"
" [NO_DEFAULT_PATH]\n"
" [NO_CMAKE_ENVIRONMENT_PATH]\n"
" [NO_CMAKE_PATH]\n"
" [NO_SYSTEM_ENVIRONMENT_PATH]\n"
" [NO_CMAKE_PACKAGE_REGISTRY]\n"
" [NO_CMAKE_BUILDS_PATH]\n"
" [NO_CMAKE_SYSTEM_PATH]\n"
" [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]\n"
" [CMAKE_FIND_ROOT_PATH_BOTH |\n"
" ONLY_CMAKE_FIND_ROOT_PATH |\n"
" NO_CMAKE_FIND_ROOT_PATH])\n"
"The NO_MODULE option may be used to skip Module mode explicitly. "
"It is also 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"
"All configuration files which have been considered by CMake while "
"searching for an installation of the package with an appropriate "
"version are stored in the cmake variable <package>_CONSIDERED_CONFIGS, "
"the associated versions in <package>_CONSIDERED_VERSIONS. "
"\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 CMake will ignore it and search from scratch."
"\n"
"When the [version] argument is given Config mode will only find a "
"version of the package that claims compatibility with the requested "
"version (format is major[.minor[.patch[.tweak]]]). "
"If the EXACT option is given only a version of the package claiming "
"an exact match of the requested version may be found. "
"CMake does not establish any convention for the meaning of version "
"numbers. "
"Package version numbers are checked by \"version\" files provided by "
"the packages themselves. "
"For a candidate package configuration file \"<config-file>.cmake\" the "
"corresponding version file is located next to it and named either "
"\"<config-file>-version.cmake\" or \"<config-file>Version.cmake\". "
"If no such version file is available then the configuration file "
"is assumed to not be compatible with any requested version. "
"A basic version file containing generic version matching code can be "
"created using the macro write_basic_config_version_file(), see its "
"documentation for more details. "
"When a version file is found it is loaded to check the requested "
"version number. "
"The version file is loaded in a nested scope in which the following "
"variables have been defined:\n"
" PACKAGE_FIND_NAME = the <package> name\n"
" PACKAGE_FIND_VERSION = full requested version string\n"
" PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0\n"
" PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0\n"
" PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0\n"
" PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0\n"
" PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4\n"
"The version file checks whether it satisfies the requested version "
"and sets these variables:\n"
" PACKAGE_VERSION = full provided version string\n"
" PACKAGE_VERSION_EXACT = true if version is exact match\n"
" PACKAGE_VERSION_COMPATIBLE = true if version is compatible\n"
" PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version\n"
"These variables are checked by the find_package command to determine "
"whether the configuration file provides an acceptable version. "
"They are not available after the find_package call returns. "
"If the version is acceptable the following variables are set:\n"
" <package>_VERSION = full provided version string\n"
" <package>_VERSION_MAJOR = major version if provided, else 0\n"
" <package>_VERSION_MINOR = minor version if provided, else 0\n"
" <package>_VERSION_PATCH = patch version if provided, else 0\n"
" <package>_VERSION_TWEAK = tweak version if provided, else 0\n"
" <package>_VERSION_COUNT = number of version components, 0 to 4\n"
"and the corresponding package configuration file is loaded. "
"When multiple package configuration files are available whose version "
"files claim compatibility with the version requested it is unspecified "
"which one is chosen. "
"No attempt is made to choose a highest or closest version number."
"\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> [major[.minor]] [EXACT] [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>/<name>*/ (W)\n"
" <prefix>/<name>*/(cmake|CMake)/ (W)\n"
" <prefix>/(lib/<arch>|lib|share)/cmake/<name>*/ (U)\n"
" <prefix>/(lib/<arch>|lib|share)/<name>*/ (U)\n"
" <prefix>/(lib/<arch>|lib|share)/<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). "
"Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is set. "
"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 all NO_* options are enabled.\n"
"1. Search paths specified in cmake-specific cache 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"
"2. Search paths specified in cmake-specific environment variables. "
"These are intended to be set in the user's shell configuration. "
"This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.\n"
" <package>_DIR\n"
" CMAKE_PREFIX_PATH\n"
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
"3. Search paths specified by the HINTS option. "
"These should be paths computed by system introspection, such as a "
"hint provided by the location of another item already found. "
"Hard-coded guesses should be specified with the PATHS option.\n"
"4. 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"
"5. 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"
"6. Search paths stored in the CMake user package registry. "
"This can be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed. "
"On Windows a <package> may appear under registry key\n"
" HKEY_CURRENT_USER\\Software\\Kitware\\CMake\\Packages\\<package>\n"
"as a REG_SZ value, with arbitrary name, that specifies the directory "
"containing the package configuration file. "
"On UNIX platforms a <package> may appear under the directory\n"
" ~/.cmake/packages/<package>\n"
"as a file, with arbitrary name, whose content specifies the directory "
"containing the package configuration file. "
"See the export(PACKAGE) command to create user package registry entries "
"for project build trees."
"\n"
"7. 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"
"8. Search paths stored in the CMake system package registry. "
"This can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed. "
"On Windows a <package> may appear under registry key\n"
" HKEY_LOCAL_MACHINE\\Software\\Kitware\\CMake\\Packages\\<package>\n"
"as a REG_SZ value, with arbitrary name, that specifies the directory "
"containing the package configuration file. "
"There is no system package registry on non-Windows platforms."
"\n"
"9. Search paths specified by the PATHS option. "
"These are typically hard-coded guesses.\n"
