[CMake] printing CMAKE_CXX_FLAGS_* based on build type

[Zdenko Podobny]

Yes, build type is known (e.g   value of ${CMAKE_BUILD_TYPE}  is shown in
output).  I use command like this:
cmake .. -G Ninja  -DCMAKE_INSTALL_PREFIX=%INSTALL_DIR%
-DCMAKE_PREFIX_PATH=%INSTALL_DIR% -DCMAKE_BUILD_TYPE=Release
