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. 196 197 Note that only the system libraries are auto-detected.
