  188. External library support:

  189. 

  190.   Using any of the following switches will allow FFmpeg to link to the

  191.   corresponding external library. 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. All the other external

  198.   libraries must be explicitly enabled.
