   1 # - Find python libraries
   2 # This module finds if Python is installed and determines where the
   3 # include files and libraries are. It also determines what the name of
   4 # the library is. This code sets the following variables:
   5 #
   6 #  PYTHON_LIBRARIES     = path to the python library
   7 #  PYTHON_INCLUDE_PATH  = path to where Python.h is found
   8 #  PYTHON_DEBUG_LIBRARIES = path to the debug library
   9 #  PYTHON_VERSION = version of python library
  10 #
  11 #  The user can set this variable to choose their preferred python
  12 #  version to be found:
  13 #
  14 #  PREFERRED_PYTHON_VERSION = preferred version of the python library
