This package is built using debbuild for Debian targets.
The Makefile included in this project helps you to do builds, but you need to have debbuild installed first.
You can install debbuild from the deb published on the GitHub project releases.
Once installed, make deb will let you build a Debian package.
For building RPMs, you just need rpmbuild. For example, on Fedora:
$ sudo dnf install rpm-build
Once installed, make rpm will let you build an RPM package.
