-# OpenCV note: the file has been extracted from CMake 2.6.2 distribution.
-# It is used to build OpenCV with CMake 2.4.x
-#
-
-# - a pkg-config module for CMake
-#
-# Usage:
-# pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
-# checks for all the given modules
-#
-# pkg_search_module(<PREFIX> [REQUIRED] <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
-#
-# 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)
