Hi Hugh, By design ExternalProject module will download and patch a project only one time.
Indeed, the ExternalProject wouldn't be able to apply a patch more than one time. It also doesn't have a way to detect if a patch has been applied. In other word, you will have to clear the project so that download / patch steps could be run cleanly. If you have specific workflow, you could run customized steps that could be able to detect if a patch has been applied, undo patch ... you would end up with some complicated logic. A different approach could be to create a git repository with the original project and apply patch on the top of it. (If it applies for you, it could be worth looking at git-svn ...)
