We’ve had similar issues with Python on Darwin. One potential cause of problems is linking against a different version of Python than the interpreter. If you install Python trough python.org or Homebrew, CMake finds that version for the interpreter, but the system one for libpython2.7.dylib.
-- Found PythonLibs: /usr/lib/libpython2.7.dylib (found version "2.7.10") <- System Python
-- Found PythonInterp: /usr/local/bin/python2.7 (found version "2.7.15") <- Homebrew Python
I’ve been told that as of version 3.12 of CMake, there will be a new interface to FindPython that will ensure consistently and differentiate between Python 2 and Python 3 (which I presume is your issue here). I don’t know if CMake supports doing different things depending on the version, but hopefully this will be resolved in the future. In the meantime (on macOS) I just unlinked the Python interpreter from /usr/local/bin.
