-# - 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.
