Subject: [PATCH] Prevent GTest and GMock from being installed with Google
 Benchmark.

When users satisfy the GTest dependancy by placing a googletest
directory in the project, the targets from GTest and GMock incorrectly
get installed along side this library. We shouldn't be installing
our test dependancies.

This patch forces the options that control installation for googletest
to OFF.
