I configured slicer.sln using cmake on windows.  
I opened the project in VS 2015, but I can’t see any source code hierarchy or any src folder.  
I compiled th solution and I got Slicer.exe generated. But still cpp files in solution manager are missing.  
Is there any other way to get those cpp files in Visual studio-\> solution manager?

The top-level solution builds all dependencies of Slicer core and Slicer core itself. You can see Slicer source files if you open `<Slicer-top-level-build-folder>\Slicer-build\Slicer.sln`.
