From 40a4871b171293d98acb40cf54be9ee9b78a3244 Mon Sep 17 00:00:00 2001
From: Samuel Martin <s.martin49@gmail.com>
Date: Wed, 6 Jun 2012 00:49:25 +0200
Subject: [PATCH 1/1] build systems: make example build optional
This patch makes example build optional for both cmake and autotools build
systems.
In order to keep the former behavior, example build is enabled by default.
