QMAKE_CXXFLAGS doesn't work

I'm reading everywhere that to add flags to the compiler we have to, inside the .pro, add command like this:

QMAKE_CXXFLAGS += -Wimplicit-function-declaration

Right, I'm under Linux 64bit, Qt5 and adding this inside my .pro doesn't change anything

It turns out that I don't see the flag inside the compilation line, and the CXXFLAGS inside the Makefile generated does not contain my flag !?

I found that sometimes qmake is a bit lazy and won't regenerate the Makefile even though the .pro has changed. Try rebuilding everything, or at least deleting the Makefile.
