-# Python libraries and interpreter detection for SALOME

-#
-# We also look for an installation of NumPy, and if found the following variables are set
-# NUMPY_INCLUDE_DIR - NumPy header location
-# NUMPY_DEFINITIONS - compiler flag
-# and are automatically appended to PYTHON_INCLUDE_DIRS (and PYTHON_DEFINITIONS resp.)
