  189. External library support:

  190. 

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

  192.   corresponding external library. All the components depending on that library

  193.   will become enabled, if all their other dependencies are met and they are not

  194.   explicitly disabled. E.g. --enable-libwavpack will enable linking to

  195.   libwavpack and allow the libwavpack encoder to be built, unless it is

  196.   specifically disabled with --disable-encoder=libwavpack.

  197. 

  198.   Note that only the system libraries are auto-detected. All the other external

  199.   libraries must be explicitly enabled.
