I am using org-mode to write source code files and tangle them out. I want to compile them using make. My problem now is that org-mode overwrites the old files every time I tangle them out, therefore also updating the time stamp - even if nothing has changed. Subsequently, when I run make, everything gets recompiled, not just the changed source code files as all time stamps have changed. Is there an option for org-mode to only overwrite source code files that get tangled out if they have truly changed? Thank you very much for your help!
