I know it doesn't exist as a preset in CMake. But take a look at the CMake files shipped with KDE4's kdelibs: those actually introduce CMAKE_C*_FLAGS_DEBIAN variables (in addition to using specific install locations, for instance). It's quite important that there is such a feature: configure and its alternatives are supposed to take CFLAGS, CXXFLAGS and family into consideration (or at least should have a mode in which they do, IMVHO). I suppose that what happens is that requesting an unknown CMAKE_BUILD_TYPE is equivalent to not requesting one at all, and also prevents downstream CMake files to pick a default preset if CMAKE_BUILD_TYPE hasn't been defined by the caller. I've had a better look at the control file I mentioned, and found the reason why $CFLAGS and $CXXFLAGS weren't being used. It turns out that if you set CMAKE_CXX_FLAGS on the commandline, it is no longer set to include $CXXFLAGS from the environment. Comments in the control file suggest that that wasn't always the case.
