- External library support:
- Using any of the following switches will allow FFmpeg to link to the
- corresponding external library. All the components depending on that library
- will become enabled, if all their other dependencies are met and they are not
- explicitly disabled. E.g. --enable-libopus will enable linking to
- libopus and allow the libopus encoder to be built, unless it is
- specifically disabled with --disable-encoder=libopus.
- Note that only the system libraries are auto-detected. All the other external
- libraries must be explicitly enabled.

- themselves, not all their features will necessarily be usable by FFmpeg.
