2 months ago Thanks, I have added “cmake_minimum_required(VERSION 3.8...3.15)”, but I'm not understanding how to use the FindPythonInterpto fix this issue.
Can you please explain it?
I'm currently stuck here:

2 months ago Oh yes, you are right, the build succeeded and it's working as expected.
I guess I can fix the CMP0148 by adding:
if(POLICY CMP0148)
cmake_policy(SET CMP0148 OLD)
endif()Just before closing this issue, I would like to know the following.
I'm still getting this part of the message, are this warnings expected since I'm on MacOS? It has somethind to do with the code signing.

2 months ago Got it, thank you very much @Tobias-Fischer
I'm already following steps from FAQ.
I started getting the error:
Then I followed the FAQ recommendation and got:
For that I upgraded
cmake_minimum_requiredfrom 3.8 to 3.28 to avoid the following error:And finally this is the error I'm getting and not knowing how to fix it.
