# Based on http://numexpr.googlecode.com/hg/FindSciPy.cmake
#
# - Find the SciPy libraries
# This module finds if SciPy is installed, and sets the following variables
# indicating where it is.
#
# TODO: Update to provide the libraries and paths for linking npymath lib.
#
# SCIPY_FOUND - was SciPy found
# SCIPY_VERSION - the version of SciPy found as a string
# SCIPY_VERSION_MAJOR - the major version number of SciPy
# SCIPY_VERSION_MINOR - the minor version number of SciPy
# SCIPY_VERSION_PATCH - the patch version number of SciPy
# SCIPY_VERSION_DECIMAL - e.g. version 1.6.1 is 10601
# SCIPY_INCLUDE_DIRS - path to the SciPy include files
