BTW, I looked into cmus.cygport of 2.11.0-2 and noticed that you
need to patch for configure to enable ffmpeg plugin as attached.
With ffmpeg plugin, many of audio formats get supported by cmus.
Furthermore, you do not need to add ffmpeg to "REQUIRES" because
the cmus package itself does not really depend on ffmpeg package
even though it depends libavcodec, libavformat, libavutil and
libswresample.
Maybe, you do not have to add any of packages to "REQUIRES"
because dependencies are added automatically by cygport in most
cases.
