[Qt-creator] Cannot override default CXXFLAGS

[Charles N Burns]

I found a way to make Qt Creator compile without RTTI and without C++
exceptions:
1) Edit qconfig.pri
Remove or comment exceptions and rtti.
For example:
    CONFIG+= debug shared stl # exceptions rtti

Clean all and recompile.

This is a workaround to the the problem of the .pro file ignoring the line:
     "QMAKE_CXXFLAGS -= -frtti -fexceptions"

Best regards,
