[PROJ] Trouble building packages for distribution

[Kristian Evers]

I had a hunch it was a problem on my end. No clue what it is though… Probably MacOS being difficult again.

I’ve pasted the output from CMake below in case anyone can see a problem in it.

Could one of you send me a copy of the files you produced? At least I can upload those in case I don’t figure
out what’s going today.
