Gbp-Pq: Name 1216.patch

[PATCH] Update cmakelists to use system googletest if available.

There is no need to use the embedded gtest code copy in Linux systems, if they already provide the googletest framework system-wide.
Search for it, and fallback to the embedded one if the system one is not detected.

This patch has been also contributed by Simon Quigley <tsimonq2@debian.org>
