I'm trying to build a codebase (with Meson), and it's yelling at me that I don't have libhandy. I found [this](https://askubuntu.com/questions/1270028/pantheon-files-depends-on-libhandy-1-0-but-it-is-not-installable-on-ubuntu-20-04) 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)?
