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