With Qt5 "proper" frameworks have been created where the headers are installed into the frameworks and QtCreator's code model just does not understand how to parse apart a framework.

In your case you need a flag “-F/Users/Shared/Toolkits/Qt-5.3.1/lib” for the compiler, and in the Header Paths in Qt Creator an entry "/Users/Shared/Toolkits/Qt-5.3.1/lib (framework path)”.

Yes. It compiles fine so the Compiler flags are correctly inserted. From the "Inspect Code Model->Project Parts->Header Paths"
 /Users/Shared/Toolkits/Qt-5.3.1/lib (include path)
/Users/Shared/Toolkits/Qt-5.3.1/lib/.. (include path)
/Users/Shared/Toolkits/Qt-5.3.1/lib/QtConcurrent.framework/Headers (include path)
/Users/Shared/Toolkits/Qt-5.3.1/lib/QtCore.framework/Headers (include path)

Can I manually add an include path?

Thanks
