Provides the following variables:
* `FFMPEG_INCLUDE_DIRS`: Include directories necessary to use FFMPEG.
* `FFMPEG_LIBRARIES`: Libraries necessary to use FFMPEG. Note that this only
includes libraries for the components requested.
* `FFMPEG_VERSION`: The version of FFMPEG found.
The following components are supported:
* `avcodec`
* `avdevice`
* `avfilter`
* `avformat`
* `avresample`
* `avutil`
* `swresample`
* `swscale`
For each component, the following are provided:
* `FFMPEG_<component>_FOUND`: Libraries for the component.
* `FFMPEG_<component>_INCLUDE_DIRS`: Include directories for
the component.
* `FFMPEG_<component>_LIBRARIES`: Libraries for the component.
* `FFMPEG::<component>`: A target to use with `target_link_libraries`.
Note that only components requested with `COMPONENTS` or `OPTIONAL_COMPONENTS`
are guaranteed to set these variables or provide targets.
