+# - Try to find the Intel Math Kernel Library

+# 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
