175 External library support:
176
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.
183
184 Note that only the system libraries are auto-detected. All the other external
185 libraries must be explicitly enabled.
186
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.
