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.
