Update CMakeLists to use add_compile_definitions (#15483)

Browse Source 
This is a newer feature introduced in CMake 3.12, which is now our
minimum version. It supercedes `add_definitions`. I've also replaced
some calls to set `CMAKE_<LANG>_FLAGS` that were used to set
definitions. This is a fairly trivial routine build maintenance that
is not intended to have any behavioral effects.
