So, here you can see the errors and use the patch.

 Jonas Bechtel

ffmpeg> ./configure --enable-libopencv
ERROR: opencv not found

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.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
