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