dpkg-buildpackage - error, how to solve this problem?

[Pawelecc]

At the outset, I would like to point out that I am not an advanced user, I use the installation guide (Installation section).

Everything goes fine until "dpkg-buildpackage":

pi@openwebrx:~/codecserver-softmbe $ sudo dpkg-buildpackage
dpkg-buildpackage: info: source package codecserver-driver-softmbe
dpkg-buildpackage: info: source version 0.0.1
dpkg-buildpackage: info: source distribution UNRELEASED

dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

How to solve this problem? I have OpenWebRX installed on Raspberry Pi 3B - image uploaded from .img from the project website.
