# FindFFMPEG
# --------
# Finds FFmpeg libraries
#
# This module will first look for the required library versions on the system.
# If they are not found, it will fall back to downloading and building kodi's own version
#
# --------
# the following variables influence behaviour:
# ENABLE_INTERNAL_FFMPEG - if enabled, kodi's own version will always be built
#
# FFMPEG_PATH - use external ffmpeg not found in system paths
# usage: -DFFMPEG_PATH=/path/to/ffmpeg_install_prefix
#
# WITH_FFMPEG - use external ffmpeg not found in system paths
# WARNING: this option is for developers as it will _disable ffmpeg version checks_!
# Consider using FFMPEG_PATH instead, which _does_ check library versions
# usage: -DWITH_FFMPEG=/path/to/ffmpeg_install_prefix
#
# --------
# This module will define the following variables:
#
# FFMPEG_FOUND - system has FFmpeg
# FFMPEG_INCLUDE_DIRS - FFmpeg include directory
# FFMPEG_LIBRARIES - FFmpeg libraries
# FFMPEG_DEFINITIONS - pre-processor definitions
# FFMPEG_LDFLAGS - linker flags
#
# and the following imported targets::
#
# ffmpeg - The FFmpeg libraries
# --------
#
# required ffmpeg library versions
