#
# - Find METIS include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(METIS
# [REQUIRED] # Fail with error if metis is not found
# )
#
# This module finds headers and metis library.
# Results are reported in variables:
# METIS_FOUND - True if headers and requested libraries were found
# METIS_INCLUDE_DIRS - metis include directories
# METIS_LIBRARY_DIRS - Link directories for metis libraries
# METIS_LIBRARIES - metis component libraries to be linked
#
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DMETIS_DIR=path/to/metis):
# METIS_DIR - Where to find the base directory of metis
# METIS_INCDIR - Where to find the header files
# METIS_LIBDIR - Where to find the library files
# The module can also look for the following environment variables if paths
# are not given as cmake variable: METIS_DIR, METIS_INCDIR, METIS_LIBDIR
