#
# Find the FFPMEG libraries
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# The following variables will be defined:
#
# ``FFMPEG_FOUND``
# True if FFMPEG found on the local system
#
# ``FFMPEG_INCLUDE_DIRS``
# Location of FFMPEG header files
#
# ``FFMPEG_LIBRARY_DIRS``
# Location of FFMPEG libraries
#
# ``FFMPEG_LIBRARIES``
# List of the FFMPEG libraries found
#
# Hints
# ^^^^^
#
# ``FFMPEG_ROOT``
# Set this variable to a directory that contains a FFMPEG installation
