I’m trying to create a DMG file using the CPack DragNDrop generator, however, for some reason, the final DMG that CMake creates does not include my `.app` file. I think this is because I’m not actually creating a Bundle using the `MACOSX_BUNDLE` and instead prepare my `.app` myself. This is because I have a few strange frameworks that I need to deal with them slightly differently.

The `.app` bundle that I create works, and it’s been deployed as well, and it is usually sitting somewhere in `build/Install/*.app`, but when I run the `cpack ..` I can see that an empty DMG is being created only with a symlink to the Application folder.

I’m wondering if there is a way to tell CMake to use my `.app` when creating the DMG?

Do you have an install rule for the `.app`? If so, can you share it? Can you also show the install log CPack gets?
