cmake: include googletest instead of its subdirectory

so its own settings can be populated properly, among other things,
`GOOGLETEST_VERSION` is set in the CMakeLists.txt in its root directory.
without it, cmake complains when interpreting

project(gtest VERSION ${GOOGLETEST_VERSION} LANGUAGES CXX C)
