Thanks a lot for your guidance. I tried Build/Slicer.sln. But I was getting “access is denied” error. After fiddling around a bit, I realized that the startup project was pointing to ALL\_BUILD. So I changed it to SlicerQReadsApp (Is this right?).

The build is working fine and I am getting the exe and it executes also. But when I try to debug, I get “DLL not found” errors with the following DLLs.  
CTKWidgets.dll  
qt5widgets.dll  
qt5guid.dll  
qt5cored.dll

Based on your answer here ([Nightly build does not run - #2 by lassoan](https://discourse.slicer.org/t/nightly-build-does-not-run/6774/2)) I tried building the whole application again. I still get the same problem. I fail to understand how the build was successful if the dlls were not found. Seeking your help once again.

Thanks a lot for your time. Really appreciate.
