  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@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.
