    Description

      Unity builds and precompiled headers can be enabled "easily" in CMake 3.16:
      https://cmake.org/cmake/help/v3.16/prop_tgt/UNITY_BUILD.html
      https://cmake.org/cmake/help/v3.16/command/target_precompile_headers.html

      They can make builds faster in some conditions, especially on CI with little parallelism and caching.
