# - Find NumPy
# Find the native NumPy includes
# This module defines
# NUMPY_INCLUDE_DIR, where to find numpy/arrayobject.h, etc.
# NUMPY_VERSION, The string version of the numpy version
# NUMPY_VERSION_MAJOR, The first number of the numpy version
# NUMPY_VERSION_MINOR, The second number of the numpy version
# NUMPY_VERSION_MICRO, The third number of the numpy version
# NUMPY_FOUND, If false, do not try to use NumPy headers.
