for me, 4292de413f lead to linker errors
if the sequential metis library was required (and the parallel is not
installed). see e.g.,
http://www.opm-project.org/CDash/viewBuildError.php?buildid=41290
The reason for this is a partial clash in the variable names which are
used by both modules. With this PR, the FindParMETIS module does not
write to any variables that are prefixed by "METIS_".
