I'm trying to build a codebase (with Meson), and it's yelling at me that I don't have libhandy. I found this question, but all links and PPAs mentioned there seem to be dead.
I need libhandy 1.0.0 or greater, and I'm on Ubuntu 20.04. How can I install it (in such a way that it will get picked up by a build system like pkgconfig)?
