Have you considered using VPATH?  It looks to me (based on this example;
I didn't try to get the tarball) that you have a good fit for it here.
Try rewriting your rule like this:

        VPATH := $(src)

        %.html: %.txt
                $(info example making $@ from $<)

and see if that works.
