Thanks for the info. Giving developers control of the `clean` target is something I'd like to see even if it does require quite a bit of thought. CMake has special commands for doing `install` so I'd expect something analogous for managing how `clean is performed`. These would be declared on a per directory basis and if the generator worked a per directory basis then we would have per directory clean targets otherwise there would just be a global clean target. >> I realise the `clean` target won't be available for all generators but >> for those that do, it would be really nice to able to do something >> like this. >> >> add_dependencies(clean CleanKLEERuntimes) > > Just as `ADDITIONAL_MAKE_CLEAN_FILES` is a make-specific solution I > think something like `ADDITIONAL_MAKE_CLEAN_COMMAND` or perhaps > `ADDITIONAL_MAKE_CLEAN_TARGET` could be offered.

Would Ninja support it too?
