I wouldn’t call that “safe globbing” myself. Personally, I find globbing to always be a poorer alternative to explicit source listings. See this post for some details. I don’t think this is something I’d like to see CMake implement (IMO, file(GLOB CONFIGURE_DEPENDS) should go away too, but all I can do is not recommend it at this point), but I won’t stop anyone from implementing it; just trying to use it in codebases I maintain.
