Does Qt offer a (guaranteed) debug definition?

Question

Does anyone know an officially supported way to include debug-build only code in Qt? For example:

#ifdef QT_DEBUG
// do something
#endif

An alternative is to write in your project file something like:

debug {
  DEFINES += MYPREFIX_DEBUG
}
release {
  DEFINES += MYPREFIX_RELEASE
}

Then you will not depend on the Qt internal definition.
