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