Fixes: #8380 This commit fixes the side-effect of PR #8211 where a 'ninja clean' would try to remove dependency folders. Changes: - Symlinks are created during build and CMake targets now depends on the symlinks. Thus, same behavior is achived with regards to dependency handling, while at the same time, the output can be cleaned as the dependencies are now attached to the symlinks. - Dependencies have been changed so that generation of json files depends on the trigger file and CMake depends upon the subdir txt file. This prevents additional CMake runs after a clean. Signed-off-by: Torsten Rasmussen <torsten.rasmussen@nordicsemi.no>
