# This module defines the following variables:

# FFmpeg_INCLUDE_<component>: where to find <component>.h
# FFmpeg_LIBRARY_<component>: where to find the <component> library
# FFmpeg_INCLUDES: 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 prefered 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
