How to set compiler flags. I want to compile my application with

In the PRO file QMAKE_CFLAGS and/or QMAKE_CXXFLAGS and their related variables.
However, you will find that /O2 is the default for a MSVC release build anyway. Setting /Ob1 defeats some of the tools used by /O2.
I am using mingw.
I wrote it like this but not working.
QMAKE_CSSFLAGS += -O2 \
-Ob1
and this is also not working
QMAKE_CSSFLAGS += /O2 \
/Ob1
CXXFLAGS and not CSSFLAGS.
