Hi Adrian,

I haven't yet, but we should try to do that, and we should also approach
the Academy Software Foundation to ask them to provide a canonical cmake
find module, I've seen too many diverse approaches.

pkg-config might actually be simplest, most GNU autoconf based ports use
that and they have been a lot easier to update. I think there was some
copying going on from the OpenEXR-finder-for-cmake from Blender, and
lots of homebrewn stuff... too much freedom in mmake.

Exactly the reason why I've for now patched our ports locally first, to
avoid a chicken-and-hen circular dependency...

Cheers,
Matthias
