Did you install UHD at all?

When you configure the gnuradio build, there are a lot of checks for
libraries and headers and a component summary at the end.

If gr-uhd is not a configured component, this usually means that the
package config file for uhd cannot be found or the libraries/headers are
not in a standard place.

Can you post the verbose for the gnuradio configure?

What install prefix did you use for uhd?
(default is /usr/local, same as gnuradio)
