#
# SYNOPSIS
#
# AX_LIB_METIS([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
# This macro searches for the METIS library in the user specified
# location. The user may specify the location either by defining the
# environment variable METIS or by using the --with-metis option to
# configure. If the environment variable is defined it has precedent over
# everything else. If no location was specified then it searches in
# /usr/lib and /usr/local/lib for the library and in /usr/include and
# /usr/local/include for the header files. Upon sucessful completion the
# variables METIS_LIB and METIS_INCLUDE are set.
#
# ACTION-IF-FOUND is a list of shell commands to run if a METIS library is
# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
# not found. If ACTION-IF-FOUND is not specified, the default action will
# define HAVE_METIS. If ACTION-IF-NOT-FOUND is not specified then an error
# will be generated halting configure.
