This issue was reported by @adrinux in:
It's not just about the make bug that was fixed, I'm arguing that it's just not good to have make files that auto run, at least at this point (changes in drush_make could make that moot).
What if I want to use a different version of CKEditor itself? Maybe there is a bug I need to avoid and it's fixed in the dev version of CKEditor, for example.
Right now I can specify the version I need in my make file, but the ckeditor.make will override my choice. And AFAIK there is nothing I can do about that. (Well, I can fork ckeditor and change the name of the make file, or manually install it. Not good.)
And if ckeditor.make breaks, it breaks the whole platform build.
Until drush make allows us to override all other make files in our own make files, having them auto run is a bad idea.
So I would again ask, can we please change the name of the make file to ckeditor.make.example? For the sort of people that use drush_make having the make file example is helpful, and it's no big deal for them to copy it over to their own make, keeping it as ckeditor.make takes away the power and flexibility of drush_make.
