+To use CMake:
+First, as CMake isn't the default on vlc populate its CMakeLists files:
+$ cd vlc && sh ./extras/buildsystem/cmake/scripts/convert_vlc_to_cmake.sh
+
+Now you can use CMake as usual:
+$ cd vlc && cmake . (or ccmake . if you want a graphical view of the settings)
+$ make [VERBOSE=1 if you want more details]
+$ make install

extras/buildsystem/cmake/include/pkg_check_modules.cmake

+# From KDELibs - BSD Licence
+# - 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_OTHERS ... all other linker flags
+#   <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
+#   <XPREFIX>_CFLAGS         ... all required cflags
+#   <XPREFIX>_CFLAGS_OTHERS  ... 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
+#
