Both Java UT and C++ UT were failing with the same CMake error from the bundled glog dependency:

CMake Error at build/_deps/glog-src/cmake/GetCacheVariables.cmake:2 (cmake_policy):
  Compatibility with CMake < 3.5 has been removed from CMake.
  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Fixed in the latest commit by adding set(CMAKE_POLICY_VERSION_MINIMUM 3.5) to src/main/cpp/CMakeLists.txt. This tells CMake to allow old cmake_policy(VERSION) calls in bundled dependencies like glog that haven't yet updated their minimum CMake version requirement.
