[Qt-creator] Additional Sources Location

[Paweł Faron]

Hello,
Is It possible to additional location of headers files after ?Importing Project?? So, the QtCreator will know where to find files includes in sources. 

I need this because my project is already huge and it uses the boost libraries. When I have boost together with my project sources, Qt creator crashes during parsing. I suspect that is related to memory usage because almost 1 GB is consumed. 

Best regards
Pawel
