    Description

      Under Windows, python debug builds cannot be identified by querying for config var Py_DEBUG, as the pyconfig.h header is static on windows (no autoconf), and debug/no-debug is determined using the preprocessor at build time.

      According to this, the most reliable way to determine if a Windows Python build is debug is:

      '_d.pyd' in importlib.machinery.EXTENSION_SUFFIXES

      sources/shiboken6/cmake/ShibokenSetup.cmake:124:  
       config_py_debug = sysconfig.get_config_var('Py_DEBUG')
