Some search hits seemed to hint that cmake already supports MacPorts & Fink, so the extra paths should already be added to `CMAKE_SYSTEM_PREFIX_PATH`.

Oh, I just see in your cmake invocation snippet that `-DCMAKE_SYSTEM_PREFIX_PATH="${prefix};/usr"` is passed. No idea how that is generated, but whereever it is might be the correct place to control the extra root vars (which might be prefix in all cases) where MacPorts specific stuff should be found.

prints:
```
Content of CMAKE_SYSTEM_PREFIX_PATH: /opt/local;/usr;/usr/local;/usr;/;/Volumes/Debian/MP9;/opt/local;//usr;/sw;/opt/local
```
/Volumes/Debian/MP9 is the target of the symlink /opt/local on my system; /sw is where Fink would be installed (not present on my system).
Your modification to FindOpenJPEG.cmake works, I've dropped trying to build with pqxx (and its dependencies) for now so I can only assume that the same mod should work there too.

The header and library search paths required for OpenJPEG, libpqxx and OpenVC are added using `//opt//local//` which is of course equivalent to `/opt/local` but easier to search-and-replace with the true install location in MacPorts' post-patch stage.
