To be able to build pam_wrapper for the selected python version e.g. Python 3.10 despite Python 3.11 also installed on the system we're passing the required Python path variables like:

-DPYTHON3_INCLUDE_DIR=/usr/x86_64-pc-linux-gnu/include/python3.11
-DPYTHON3_LIBRARY=/usr/x86_64-pc-linux-gnu/lib/libpython3.11.so
-DPYTHON3_SITELIB=lib/python3.11/site-packages

which results in a CMake failure since 1.1.5:

CMake Error at src/python/python3/CMakeLists.txt:35 (python_add_module):
  Unknown CMake command "python_add_module".

since the python_add_modules relies on find_package(PythonLibs 3) which never gets called when setting the python paths manually, this was probably working for 1.1.4 since it also included python2 checks.

A dirty hack to allow the above to succeed:

FindPythonLibs is also deprecated since 3.12 and FindPython3 should be used instead so the proper fix would probably be to rework the checks completely and use FindPython3 instead, I'm no CMake expert though so I'm unable to do this myself to be able to contribute a proper fix.
