From ba994f4404b6eadcab4e0ead46ef4d3ffeceb024 Mon Sep 17 00:00:00 2001
From: Antoine Villeret <avilleret@users.sourceforge.net>

Subject: lots of changes ! 1. switch to a new build system based on automake
 (because we need to check for some lib on ./configure before make) 2. sort
 files in different directory 3. add some new features (some of them need
 OpenCV >= 2.4.5)
