[CMake] How to create folders like "Source Files" through CMake

[Pavan Podila]

Hello everyone,
    I notice that when we specify the sources, CMake nicely puts the 
.cpp files under a logical folder "Source Files" in VS.NET. Same is true 
for the "CMake Rules" folder. I want to put some of the moc_ files 
generated by MOC, under a "Generated Files" logical folder. Is there 
anyway to specify that in CMake ?

Thanks,
Pavan
