#
# find_package(PythonDev)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# PYTHON_EXECUTABLE If this is set to a path to a Python interpreter
# then this module attempts to infer the path to
# python-config from it
# PYTHON_CONFIG Set this variable to the location of python-config
# if the module has problems finding the proper
# installation path.
#
# Variables defined by this module:
#
# PYTHONDEV_FOUND System has Python dev headers/libraries
# PYTHON_INCLUDE_DIR The Python include directories.
# PYTHON_LIBRARIES The Python libraries and linker flags.
