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