**Edit** : It seems like upgrading CMake to the latest stable version seems to have fixed the problem.

Can you try the build with CMake 3.15.1 or newer?

I have upgraded to CMake 3.16.3 (via `brew`) and that seems to have fixed the problem! Thanks for the help anyway! Maybe the upgrade from 10.15.1 to 10.15.3 messed up something...
