Looks good to me. I was initially confused why we were creating a list of paths to use as `DEPENDS` later rather than using `add_dependencies` as we go, but I now see in the CMake documentation that `add_dependencies` is only for top-level targets to depend on other top-level targets, so a list is in fact needed and this PR as-is makes sense.
