Hello,

I successfully compiled catalyst (v5.6.3) from a source tree generated through:

python catalyze.py -i Editions/Base/ -i Editions/Enable-Python -o Users/bknaepen/Sources/catalyst

After compiling and typing make install, everything gets installed in /Users/bknaepen//catalyst/build/CMakeFiles/\_\_macos\_install

Is there a way to specify a different install directory? I have tried to set CMAKE\_INSTALL\_PREFIX in various ways but just cannot achieve it.

Regards,  
Bernard.

That’s an artifact of the macOS `.app` packaging. I don’t think `catalyze.py` has been tested on macOS, but turning off the GUI and/or using a UNIX style install (I forget the flag for it) should make that go away.
