DEFINES in qmake adds additional defines (-D) to the cflags used to build C++ affect code compiled with them. QtDeclarative was not compiled with these defines, so your adding them won’t affect console.log (whose C++ implementation lives inside QtDeclarative).

If you don’t want debug prints, you need to install a message handler (you say you’ve tried this and it doesn’t work, I can’t answer why that would be the case, it should work, as it uses the same infrastructure).
