170 External library support:
172 Using any of the following switches will allow Libav to link to the
173 corresponding external library. All the components depending on that library
174 will become enabled, if all their other dependencies are met and they are not
175 explicitly disabled. E.g. --enable-libwavpack will enable linking to
176 libwavpack and allow the libwavpack encoder to be built, unless it is
177 specifically disabled with --disable-encoder=libwavpack.
179 Note that only the system libraries are auto-detected. All the other external
180 libraries must be explicitly enabled.
182 Also note that the following help text describes the purpose of the libraries
183 themselves, not all their features will necessarily be usable by Libav.

380 If you think configure made a mistake, make sure you are using the latest
381 version from Git. If the latest version fails, report the problem to the
382 libav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.
384 if disabled logging; then
386 Rerun configure with logging enabled (do not use --disable-logging), and
387 include the log this produces with your report.
391 Include the log file "$logfile" produced by configure as this will help
