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
libav-user at libav.org mailing list or IRC #libav on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
make: *** [configure-stamp-static] Error 1
-----
The link error of a library link to a "as-needed" option is the cause.
We can confirm this from config.log.

This problem is corrected when we change the turn of an option.
