Merge lp:~smspillaz/compiz-core/compiz-core.fix_964248 into lp:compiz-core

[Sam Spilsbury]

Fix LP#964248 - Build GTest locally

== Problem ==

See LP#964248 - If libgtest isn't installed then FindGTest will fail, but Ubuntu doesn't ship the gtest library anymore so we need to compile it locally

== Solution ==

Added CMake commands to compile gtest locally, link to that

== Test ==

make

[Daniel van Vugt (vanvugt)]

Works OK, though possibly needs some more indentation inside if/endif.
