With the CMAKE_DISABLE arg at line 221, can the CMAKE_IGNORE_PATH for izumi builds at line 224 be removed? The conda environment issue sounds like an issue I had on izumi, so the IGNORE_PATH arg was added.

I'm an idiot - I didn't even think of Izumi, and that's a good question. Let me try things out and report back. Got a few other things I need to focus on tonight, so it may be tomorrow.

(I'm embarrassed to say I didn't even check out the other -DCMAKE args!)
