From 7d6417bbb3e304d9e7aaa61b6731ecafc3329d4e Mon Sep 17 00:00:00 2001
From: Bastien Montagne <montagne29@wanadoo.fr>
Date: Thu, 15 Nov 2012 17:31:18 +0000
Subject: Another nuch of fixes/improvements to install_deps script, among
 which: *New $INST variable to easily change the installation root dir of
 compiled libs. *Better handling of versions for debian (DEB) too (and fix a
 bug for fedora (RPM) ones). *Enhancements/fixes to compile_FOO funcs: **Most
 notable, we now can force a recompile when we change something into these
 funcs, so user will always have latest-instructions compiled libs (else, he
 would have have to manually remove lib dirs under $INST...) *General naming
 cleanup inside script (still wip).

Also adding boost date_time lib to linux in cmake file (why wasn't it there???).
