# - Find python libraries
# This module finds if Python is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
# PYTHONLIBS_FOUND = have the Python libs been found
# PYTHON_LIBRARIES = path to the python library
# PYTHON_INCLUDE_PATH = path to where Python.h is found
# PYTHON_DEBUG_LIBRARIES = path to the debug library
#
