# CMake module to search for the vlc libraries.
#
# WARNING: This module is experimental work in progress.
#
# This module defines:
# VLC_INCLUDE_DIRS = include dirs to be used when using the vlc library.
# VLC_LIBRARY_DIRS = directories where the libraries are located.
# VLC_LIBRARY = full path to the vlc library.
# VLC_CORE_LIBRARY = full path to the vlccore library.
# VLC_VERSION_STRING = the vlc version found
# VLC_VERSION_MAJOR
# VLC_VERSION_MINOR
# VLC_VERSION_PATCH
# VLC_VERSION_EXTRA
# VLC_FOUND = true if vlc was found.
#
# This module respects:
# LIB_SUFFIX = (64|32|"") Specifies the suffix for the lib directory

### Look for the include files.
