Does RelWithDebInfo do what you want? I have in the past taken one of the “alternative targets” (RelWithDebInfo or MinSIzeRel) and adjusted the flags for that target until it suited my specific needs, but I don’t necessarily claim that is the right way to go in all cases. Also be aware that the default optimization level can differ slightly with each of these build types. In the end, it’s probably best to survey the current settings for each build type and see if one is close to what you want.
