 ERROR: opencv not found using pkg-config

 If you think configure made a mistake, make sure you are using the latest
 version from Git.  If the latest version fails, report the problem to the
 ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
 Include the log file "ffbuild/config.log" produced by configure as this
 will help
 solve the problem.
