Ah, so you are using the independent from KDE, for a Qt-only project. That's 
nice :-) 
There are probably not that many projects out there which do this (mainly 
probably Phonon).
Can you please post your CMakeLists.txt which does the automoc-handling ?

Ok, I see the issue. Strange that the "C:" is split away from the cpp file, 
but not from the directories ("grantlee_core_library").
So you do this with NMake makefiles in a normal cmd.exe, no mingw or something 
like this, right ?

Windows developers, Patrick: have you seen this issue before somewhere ?
