On https://drive.google.com/open?id=0B8Ca7kayrO57WFoxSGQ2MDBia0U&authuser=0 you get my short example with CPP code
I have set a environmental variable QTDIR which points to my Qt directory in my case /Application/Qt/5.3/clang_64

Sure:

g++ -o main.o -c -O2 -std=c++11 -Wall -DQT_CORE_LIB -DQT_GUI_LIB -I/Applications/Qt/5.3/clang_64/include/QtGui -I/Applications/Qt/5.3/clang_64/include -I/Applications/Qt/5.3/clang_64/include/QtCore -F/Applications/Qt/5.3/clang_64/lib main.cpp
main.cpp:1:10: fatal error: 'QApplication' file not found
#include <QApplication>
         ^
1 error generated.

Thanks I replace it in my SConstruct
