That's what I though too, but without the line I added the extra modules aren't found. Where is `kdevpython_SOURCE_DIR` defined, did I overlook it?

Indeed, on Linux the original code seems to work, so the use of the dedicated finder could be limited to `if(APPLE)`. I did take a quick look at the stock FindPythonInterp (and FindPythonLibs) but without more feedback from the CMake ML and lacking intimate knowledge of "cmaking" (which seems to be required here) I preferred to follow the only hint I'd gotten on that ML.

I'm a bit surprised, in fact. Usually asking on the CMake ML is very effective when someone replies to tell you what you're doing wrong. Maybe there *is* a bug here (though it's more likely the fact I'm trying to find a Python version installed through MacPorts that's not been foreseen).

Yep - see my same thing reply :)
