Oh, I wasn't aware of that, that's good to know.

I think disabling sandboxing would be overkill here. The cmake script
tries to find out whether to use 'ps -uaxww' or 'ps -ef' to find a
running process. There is already a hardcoded command for Linux some
lines above that in the CMakeLists.txt, so that could be extended with a
fixed command for Darwin/Mac OS X.
