From 75372b8088c20474497b79ec6cf1e99f2d17f56d Mon Sep 17 00:00:00 2001
From: Ismo Puustinen <ismo.puustinen@intel.com>

Subject: [PATCH] buildsystem: do not assume building in source tree.

Use $(top_srcdir) as reference for include paths and buildtime scripts.
Otherwise compilation outside of project root directory will fail
because header and script paths are wrong.

To reproduce: mkdir b; cd b; ../configure; make

Upstream-status: Accepted [https://git.linuxtv.org//v4l-utils.git/commit/?id=bd98c9a99bffc8d44c54859345e4dfee0ada4275]
