Single-file C/C++ public-domain/open source libraries with minimal dependencies
I've lately found myself wondering why there isn't a C/C++ tool comparable to npm, cargo, cpanm, etc. There's more C/C++ code in the wild than most languages, but it's not easy to find, not easy to install, not easy to update (though that's a problem in the npm ecosystem, too), and not easy to integrate. A good package manager would go a long way toward modernizing the C ecosystem, I think.
