Currently there're 39 packages have their local use flag "cuda" (including dev-libs/cudnn:cuda11-5.) Let us promote them to a single global USE flag. Most of them should fall into that sole new flag. There's bug #619460, but it is different from this. I don't have any nVidia card, but am glad to help Gentoo. ;) Thanks. Reproducible: Always
