Hi, I had couple of issues and this was one of them. You have to install UHD first,
https://files.ettus.com/manual/page_install.html, see this link & install using those commands & retry. I followed same & I didn't get this error again. If you have any difficulty following above link, use these commands:
sudo apt update
sudo apt install uhd-host

from gr-radar.

The other errors I faced included, No package 'Qt5Qwt6' found. I tried several ways but couldn't solve this.

Since you didn't face this error, how did you install Qwt?
-- Checking for module 'Qt5Qwt6'
-- Found Qt5Qwt6, version 6.1.4
-- QWT Version: 6.1.4
-- Found Qwt: /usr/lib/libqwt-qt5.so
(From your comment)

Kindly help me with this. Thanks.
