   9 Static linking userspace programs such as MPD against libaudiofile fails if
  10 FLAC is available, because libaudiofile is linked against FLAC, but this isn't
  11 expressed in the pkg-config file:

  25 The Libs.private field is specifically designed for such usage:

  27 From pkg-config documentation:
  28
  29   Libs.private:

  31      This line should list any private libraries in use.  Private
  32      libraries are libraries which are not exposed through your
  33      library, but are needed in the case of static linking.
  34
  35 Therefore, this patch adds a reference to FLAC as well as to lcov in the
  36 Libs.private field of the pkg-config file.
