Cherif,
Did you install gr-ettus? Unless you are using UHD on master branch (4.0), you need gr-ettus. I installed UHD3.15LTS on Ubuntu 18.04 without PYBOMBS and it works fine.

Make sure that you've used `-DCMAKE_INSTALL_PREFIX=` with a prefix that contains a path that GNU Radio looks into; GRC prints the paths into the console when it's started!
