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 (deprecated)
PYTHON_INCLUDE_DIRS        - path to where Python.h is found
PYTHON_DEBUG_LIBRARIES     - path to the debug library (deprecated)
PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)

The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this variable before calling find_package(PythonLibs).

If you’d like to specify the installation of Python to use, you should modify the following cache variables:

PYTHON_LIBRARY             - path to the python library
PYTHON_INCLUDE_DIR         - path to where Python.h is found
