 after reading the documentation,


 [[[https://guide.macports.org/}}}

 i cannot find the answer. i have built and installed my own versions of
 ffmpeg, x265,x264 libs and binaries.  and placed links to them in the
 default macports locations /opt/local/bin, /lib,



 now i'm installing a opencv which has dependencies on ffmpeg and x265 and
 it fails to install opencv because of the "foreign" libs already.

 i'd rather force macports to use my lib than force it to skip a
 dependency.

 can someone update the documention?
