# FindFFmpeg
# ----------
#
# Find the native FFmpeg includes and libraries
#
# This module defines the following variables:
#
# FFmpeg_INCLUDE_<component>: where to find <component>.h
# FFmpeg_LIBRARY_<component>: where to find the <component> library
# FFmpeg_INCLUDE_DIR: aggregate all the include paths
# FFmpeg_LIBRARIES: aggregate all the paths to the libraries
# FFmpeg_FOUND: True if all components have been found
#
# This module defines the following targets, which are preferred over variables:
#
# FFmpeg::<component>: Target to use <component> directly, with include path,
# library and dependencies set up. If you are using a static build, you are
# responsible for adding any external dependencies (such as zlib, bzlib...).
#
# <component> can be one of:
# avcodec
# avdevice
# avfilter
# avformat
# avutil
# postproc
# swresample
# swscale
#
