According to the page you link to system paths are searched before directories 
added via PATHS. Considering we base our search on parameters already set 
(GTEST_ROOT and GMOCK_ROOT) we probably should use HINTS instead of PATHS as 
directories specified with HINTS take precedence over system paths.

Can you run this experiment ? That is
- change PATHS to HINTS in the line above and the other find_path calls 
further down the macro
- reinstall gtest 1.7.0
- rerun ninja
- verify it still finds your correct local googletest instead of the system 
installed one.
