1) git clone --recursive https://github.com/alex-free/dreamcast-cdi-burner
2) cd dreamcast-cdi-burner
3) ./build
All build dependencies will be downloaded (if you have the APT package manager, so Ubuntu/Debian/derivatives like Pop!OS). Feel free to open a pull request to add support for other package managers/distributions.
All software dcdib depends on will be compiled and then made portable by my PLED tool.
A release .zip file will be generated by the build script. A release directory will also be created, allowing you to immediately use the DCDIB open source toolkit.
If you want to clean your DCDIB source tree of all built binaries/releases, simply execute ./build clean.
