Unless qmake gained some new flag for Qt5, qmake only differs between release and debug and debug means using the debug C runtime and a corresponding qt debug build. Your only options are to either get a debug qt version or setup the necessary compiler flags for generating debug symbols (but not linking against the debug C runtime) yourself. For MSVC thats /Zi passed to the compiler. Andreas
