If you have questions, please read the FAQ.
You don't need to do this. If you just want to use Goonto, read the FAQ entry How do I run Goonto?
Debug builds (cargo build) differ slightly from release builds (cargo build --release).
Notably, you can run Goonto without elevated permissions. This may break some
features.
$ cargo build --release
$ target/release/goonto
Goonto has a few additional dependencies on Linux. They're listed in the Release build workflow.
It's just standard X11 libs, pkg-config, and cmake. You probably have them
installed already.
Then:
$ cargo build --release
$ target/release/goonto
