By reading the docs.

yes - but its unusable :(
more easy correct Makefile manually

Why ?

IMO it is easier to write qmake QMAKE_CXXFLAGS_DEBUG+="-g -O2" (or even put the statement directly into the project file if you want than action to persist) than correcting Makefiles manually.

Moving thread to newbie!

its unusable for me
case i dont know contents of pro file
and if i want use this flag i must know if is debug or release version
and if it multi threads app

i must use only command like
qmake -o Makefile "QMAKE_CFLAGS_DEBUG += -O3" pro.pro

btw how to change in QMAKE_CFLAGS_RELEASE correct -O2 to -O3
i can't even if i use pro file?

Then set both QMAKE_CXXFLAGS_RELEASE and QMAKE_CXXFLAGS_DEBUG.

QMAKE_CXXFLAGS_RELEASE -= -O2
QMAKE_CXXFLAGS_RELEASE += -O3
