Those libs mentioned as 'missing' in the ticket are not
supposed to be public, since they're MinGW-w64 system libs;
at least here, they *are* in sdl2.pc, under Libs.private.
And the proper way to get pkg-config to recognize that is
to set the --static flag.

IIRC, this should only be a problem when building as static,
and as mentioned above, that means you should be setting
--pkg-config-flags="--static" when configuring FFmpeg.
