New description:

 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?

Comment:

 We strongly discourage modifying files in `/opt/local` manually and we do
 not support linking against your own pre-installed versions for the same
 reasons we discourage using `/usr/local` (see wiki:FAQ#usrlocal).

 If you need special copies of ffmpeg, x265 and x264, I suggest you create
 a local portfile repository (see https://guide.macports.org/#development
 .local-repositories) that contains Portfiles for these ports and modify
 the Portfiles to suit your needs.

 We do not support forcing macports to use your custom built copy. As
 you've already noticed, you can skip the dependency.

 Since we do not support this use-case, I will also not update the
 documentation to include it.
