# - Try to find the Intel Math Kernel Library
# Once done this will define
#
# MKL_FOUND - system has MKL
# MKL_ROOT_DIR - path to the MKL base directory
# MKL_INCLUDE_DIR - the MKL include directory
# MKL_LIBRARIES - MKL libraries
#
# There are few sets of libraries:
# Array indexes modes:
# LP - 32 bit indexes of arrays
# ILP - 64 bit indexes of arrays
# Threading:
# SEQUENTIAL - no threading
# INTEL - Intel threading library
# GNU - GNU threading library
# MPI support
# NOMPI - no MPI support
# INTEL - Intel MPI library
# OPEN - Open MPI library
# SGI - SGI MPT Library
