Problem in building SlicerCustomAppTemplate

Thank you for this information.
I followed the steps (without modifying any CMake variables from CMakeLists.txt) and it took lot of time to build All_Build project.
But after it, I observed there was no Slicer-superbuild directory in my bin folder, only Slicer-build directory was there. So I built the Slicer.sln from Slicer-build and it was succeeded, run the Slicer.exe successfully.
But In my application,I can not load Dicom data (maybe because Slicer_BUILD_DICOM_SUPPORT is OFF).
So what should I do now to turn some modules ON without doing this whole procedure of build again?
