[Development] Problems porting Qt5.15 to Qt 6.2 for OS/2

[Fabian Kosmale]

Hi,

to expand on what Alexey said: Without linking against Qt::Gui, you will 
not have qpa in your include paths, which in turn means that 
QPlatformIntegrationFactoryInterface_iid  won't be macro-expanded to the 
string literals that is defined in qplatformintegrationplugin.h. In 
turn, moc will complain because it is expecting a string literal after IID.

Regards,
Fabian
