So that's what I did. I cloned every single library from NthDimension (the creators of the Signet) and pulled in all the fixes from various repos. I documented at least the build instructions.
After hours and hours of frustration, I did not have the energy to fix all the compiler warnings tonight. I would like to. I'd also like to set up CI/CD jobs to automate the build process.
Honestly, I'm surprisingly okay with taking over all of this responsibility.
