Make indexers aware of DEFINES specified in pro files

We have the project with definitions in a pro-file

TEMPLATE = app
TARGET = myapp
DEFINES = MY_DEBUG_MESSAGE

And in a program body

#ifdef MY_DEBUG_MESSAGE
#define myDebug(msg, args...) qDebug(msg, ##args)
#else
#define myDebug(msg, args...) qt_noop()
#endif

int main()
{
...
myDebug("As Is");
......
}

Eclipse, will always highlight,
#define myDebug(msg, args...) qt_noop()
As the active code, and will compile as
#define myDebug(msg, args...) qDebug(msg, ##args)

The consequence of it is the fact that Q_XXX defines (which are defined in qt pro files) are not recognized
