-#
-# When the 'REQUIRED' argument was set, macros will fail with an error

+.. command:: pkg_check_modules
+
+ Checks for all the given modules. ::
+
+    pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
+                      [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
+                      <MODULE> [<MODULE>]*)
+
+
+ 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.
+
+ By default, if :variable:`CMAKE_MINIMUM_REQUIRED_VERSION` is 3.1 or
+ later, or if :variable:`PKG_CONFIG_USE_CMAKE_PREFIX_PATH` is set, the
+ :variable:`CMAKE_PREFIX_PATH`, :variable:`CMAKE_FRAMEWORK_PATH`, and
+ :variable:`CMAKE_APPBUNDLE_PATH` cache and environment variables will
+ be added to ``pkg-config`` search path.
+ The ``NO_CMAKE_PATH`` and ``NO_CMAKE_ENVIRONMENT_PATH`` arguments
+ disable this behavior for the cache variables and the environment
+ variables, respectively.
+
+ It sets the following variables: ::
+
+    PKG_CONFIG_FOUND          ... if pkg-config executable was found
+    PKG_CONFIG_EXECUTABLE     ... pathname of the pkg-config program
+    PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
+                                  (since CMake 2.8.8)
+
+ 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 ``pkg-config`` was called with the ``--static``
+ option. ::
+
+    <XPREFIX>_FOUND          ... set to 1 if module(s) exist
+    <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>
