integration tests using cps files pointing to libraries installed in ubuntu 22

[tylerjw]

1. setup docker based on ubuntu 22
2. install some libraries from ubuntu in that container
3. copy cps files from https://github.com/tylerjw/ubuntu-jammy-cps to some directory here
4. write integration tests that verify cps-config works the same way pkg-config works with those packages

To post an update on what I've been doing. I created a tool to generate CPS files from PC files. You can find that here. https://github.com/tylerjw/cps-deps/tree/main

Also, https://github.com/tylerjw/ubuntu-jammy-cps now includes a Dockerfile that'll generate cps files and a ton more files.

I like this! And honestly the ability to convert a pc file into CPS sounds in-scope for cps-config as well
