"\"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 "

|
|
"If the file is found, it is read and processed by CMake. "

"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> [major[.minor[.patch]]] [EXACT] [QUIET]\n"
|
|
" [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]\n"
|

"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"
|
|
"If the package configuration file cannot be found CMake "

"will generate an error describing the problem unless the QUIET "

"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"
|
|
"When the \"[major[.minor[.patch]]]\" version argument is specified "
|
|
"Config mode will only find a version of the package that claims "
|
|
"compatibility with the requested version. "
|
|
"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 confguration 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. "
|
|
"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 = requested major version, if any\n"
|
|
" PACKAGE_FIND_VERSION_MINOR = requested minor version, if any\n"
|
|
" PACKAGE_FIND_VERSION_PATCH = requested patch version, if any\n"
|
|
"The version file checks whether it satisfies the requested version "
|
|
"and sets these variables:\n"
|
|
" PACKAGE_VERSION = package version (major[.minor[.patch]])\n"
|
|
" PACKAGE_VERSION_EXACT = true if version is exact match\n"
|
|
" PACKAGE_VERSION_COMPATIBLE = true if version is compatible\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 = package version (major[.minor[.patch]])\n"
|
|
" <package>_VERSION_MAJOR = major from major[.minor[.patch]], if any\n"
|
|
" <package>_VERSION_MINOR = minor from major[.minor[.patch]], if any\n"
|
|
" <package>_VERSION_PATCH = patch from major[.minor[.patch]], if any\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 "

" <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 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. "

|
|
" 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 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"
