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

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