My only concern is that there is no way then to select another python 
version if there should be a problem with the latest installed one.
With macports one can install different versions and select an active 
one. But cmake's FindPython3 seems not to honor that choice and returns 
always the latest one installed.

I've tried to find out which version is actually used by LyX.
On MacOS LyX does not use the version found by CMake; At least not for 
running the reconfigure script. This uses the python3 command which is 
set by macports and which can be different from the one returned by 

Maybe there are other locations in lyx where another python is used?
