-# METIS Find Module for MSTK
-# Shamelessly stolen from Amanzi open source code https://software.lanl.gov/ascem/trac
-#
-# Usage:
-# Control the search through METIS_DIR or setting environment variable
-# METIS_ROOT to the METIS installation prefix.
-#
-# This module does not search default paths!
-#
-# Following variables are set:
-# METIS_FOUND (BOOL) Flag indicating if METIS was found
-# METIS_INCLUDE_DIR (PATH) Path to the METIS include file
-# METIS_INCLUDE_DIRS (LIST) List of all required include files
-# METIS_LIBRARY_DIR (PATH) Path to the METIS library
-# METIS_LIBRARY (FILE) METIS library
-# METIS_LIBRARIES (LIST) List of all required METIS libraries
