doesn't work.
I think you are running into the old issue that faces should be quoted
in font-lock keywords, else they will be treated as variables. For
historical reasons, font-lock-constant-face (etc) as well as being a
face, is a variable whose value is that face.
Instead, try
(font-lock-add-keywords nil '(("foo" . 'highlight)))
