I made a front-end Pascal library, and and Object Pascal wrapper for
libmosquitto a couple of years ago. It's available here. It's know to work
on Linux, Windows and macOS at least. It's against libmosquitto 1.x. Not
sure if 2.x got released meanwhile. I can update things if needed. (Pull
requests are welcomed.)

It's available here:

Before I started working on this, I've also seen some Delphi
library/component that was a fully Pascal implementation of the MQTT
protocol but it was full of newschool Delphi-isms, which I disliked, so I
did my own solution instead. But what I want to say with this, there are
definitely other options out there too with different pros/cons.
