Drop custom gtest configuration

We currently hardcode gtest include directories in a few places. This doesn't seem to be necessary, and should be taken care of by gtest itself at https://github.com/google/googletest/blob/e588eb1ff9ff6598666279b737b27f983156ad85/googletest/CMakeLists.txt#L118

Related to #951
