From c9ca4538978121d953d3d07f94a73ce3fef6cc74 Mon Sep 17 00:00:00 2001
From: eschnett <eschnett@043a8217-7a68-40fe-abfd-36aa7d4fa6a8>
Date: Mon, 19 Dec 2011 14:42:06 +0000
Subject: Don't overwrite OPENMPI_INC_DIRS and OPENMPI_LIB_DIRS.

Also reformat configure.sh to look similar to the other ExternalThorns.
