ENH: Re-arranged code to test adding a custom command to generate a source file after the file has been added to a target. This is supported by the current implementation because of the use of source lists in the target implementation. When we later convert to creating cmSourceFile instances immediately for the target we need to make sure the mentioned case still works.
