| # - Find python libraries | ||
| # This module finds the libraries corresponding to the Python interpreter | ||
| # FindPythonInterp provides. | ||
| # This code sets the following variables: | ||
| # | ||
| # PYTHONLIBS_FOUND - have the Python libs been found | ||
| # PYTHON_PREFIX - path to the Python installation | ||
| # PYTHON_LIBRARIES - path to the python library | ||
| # PYTHON_INCLUDE_DIRS - path to where Python.h is found | ||
| # PYTHON_MODULE_EXTENSION - lib extension, e.g. '.so' or '.pyd' | ||
| # PYTHON_MODULE_PREFIX - lib name prefix: usually an empty string | ||
| # PYTHON_SITE_PACKAGES - path to installation site-packages | ||
| # PYTHON_IS_DEBUG - whether the Python interpreter is a debug build | ||
| # | ||
| # Thanks to talljimbo for the patch adding the 'LDVERSION' config | ||
| # variable usage. | ||

Please, no vendored and totally outdated cmake stuff.
Pybind11 supports cmake config mode for ages, and does not require any external helpers.

This is a patch that has been making the rounds for years as part of distro-packaged netgen-- I agree, it's pretty heavy/ugly. I used it only because I knew it worked. I'll do something better.
The general problem with CMake is that it is mostly unaware that RedHat distributions exist at all, and there does not seem to be any release testing against RH distros. A lot of the trouble is RedHat's own fault, of course, and CMake authors have been very responsive to suggested fixes. But that does mean that a bleeding-edge CMake is needed to build things, so I have generally opted for workarounds if they're not too awful.
