Thanks for your advice. > Doesn't the DEBUG variant of the flags, e.g. CMAKE_CXX_FLAGS_DEBUG, and > other related variables - perhaps in connection with CMAKE_BUILD_TYPE - > work for you? Regarding CMAKE_CXX_FLAGS and CMAKE_CXX_FLAGS_RELEASE, is CMAKE_CXX_FLAGS used if no build type is specified and CMAKE_CXX_FLAGS_RELEASE used if the build type is "Release"? If that is so, I plan to assign my desired release options to CMAKE_CXX_FLAGS_RELEASE and assign that variable to CMAKE_CXX_FLAGS. That way, a release build will happen by default (no build type specified) or if "Release" is specified. I can handle debug builds using CMAKE_CXX_FLAGS_DEBUG. Am I understanding correctly?
