I think there are a few points of confusion here. First, you said that
you tried to build GNU Radio before installing UHD, but I'm guessing
that was a mistake since you show here that you've installed UHD. If
you build GNU Radio before installing UHD, you shouldn't expect it to
know about UHD.

(Also, it's "GNU Radio"  and not just "GNU" -- GNU refers to the
bigger GNU project at www.gnu.org.)

When installing a project by hand like this, you are not using the
Debian system, so there's no reason it will be found by dpkg.

That output tells you that it didn't find the UHD library, which could
be for many reasons.

I would recommend trying PyBOMBS to install GNU Radio instead:
