From 08aa9a26779d4ede3de7857fafd03bd6331ba948 Mon Sep 17 00:00:00 2001 From: Philippe Proulx Date: Mon, 6 Nov 2017 15:46:03 -0500 Subject: [PATCH] configure.ac: add --disable-examples option to not build/install examples Some environments and distributions do not need the LTTng-UST examples to be built because they remove them anyway. Continue to build them by default, but add --disable-examples to explicitly disable them.
