# - Find the NumPy libraries
|
|
# This module finds if NumPy is installed, and sets the following variables
|
|
# indicating where it is.
|
|
#
|
|
# TODO: Update to provide the libraries and paths for linking npymath lib.
|
|
#
|
|
# NUMPY_FOUND - was NumPy found
|
|
# NUMPY_VERSION - the version of NumPy found as a string
|
|
# NUMPY_VERSION_MAJOR - the major version number of NumPy
|
|
# NUMPY_VERSION_MINOR - the minor version number of NumPy
|
|
# NUMPY_VERSION_PATCH - the patch version number of NumPy
|
|
# NUMPY_VERSION_DECIMAL - e.g. version 1.6.1 is 10601
|
|
# NUMPY_INCLUDE_DIRS - path to the NumPy include files
