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-libwavpack will enable linking to libwavpack and allow the libwavpack encoder to be built, unless it is specifically disabled with --disable-encoder=libwavpack. Note that only the system libraries are auto-detected. All the other external libraries must be explicitly enabled.
