[FFmpeg-devel] Configure Script change request to support libcdio on macOS

[桃源老師]

Hello,

In fact, I'm not a kind of ffmpeg developer at all.  While trying to link libcdio library with ffmpeg, I just happened to find out the way...

So I'm not sure I can answer any question about this configure script change...


I have tried to use libcdio function with ffmpeg on macOS. Then I get an information from libcdio team.  That is ffmpeg configure script should read libcdio's pkgconfig file, libcdio.pc.

So I tried and error, then found that the below change should be done to link libcdio library with ffmpeg on macOS.

Please review it and make it acceptable for everyone...
