189 External library support:
191 Using any of the following switches will allow FFmpeg to link to the
192 corresponding external library. All the components depending on that library
193 will become enabled, if all their other dependencies are met and they are not
194 explicitly disabled. E.g. --enable-libwavpack will enable linking to
195 libwavpack and allow the libwavpack encoder to be built, unless it is
196 specifically disabled with --disable-encoder=libwavpack.
198 Note that only the system libraries are auto-detected. All the other external
199 libraries must be explicitly enabled.
