Should work. Are you sure there is not typo ? > I rebuilt everything, ensured that the CMAKE_BUILD_TYPE variable in the > cache is set to "Debug," I'm not quite sure about case-sensitivity here, would have to check. Does it work if you set the buildtype tp "DEBUG" instead of "Debug" ? > and built the library using verbose Makefiles.

No, it's not. Non-cache variables basically shadow the cache variables. You know that the variables above are for C, and there is the same set of variables also for C++ ? CMAKE_CXX_FLAGS_DEBUG etc. Could it be that you have a C++ project and you did set only the C variables ?
