#.rst:
# FindFFMPEG
# ----------
#
# Find the native FFMPEG includes and library
#
# This module defines::
#
# FFMPEG_INCLUDE_DIR, where to find avcodec.h, avformat.h ...
# FFMPEG_LIBRARIES, the libraries to link against to use FFMPEG.
# FFMPEG_FOUND, If false, do not try to use FFMPEG.
#
# also defined, but not for general use are::
#
# FFMPEG_avformat_LIBRARY, where to find the FFMPEG avformat library.
# FFMPEG_avcodec_LIBRARY, where to find the FFMPEG avcodec library.
#
# This is useful to do it this way so that we can always add more libraries
# if needed to ``FFMPEG_LIBRARIES`` if ffmpeg ever changes...
