Speaking of which, is there any good package management system for modern C/C++?

Arne Mertz has a Vagrant box for people who want to experiment with a "4C" development environment (Clang, Cmake, Conan, Clion).
EDIT: Also worth noting that a common response I've heard to "I need a better manager for my dependencies" is "you have a system package manager for a reason."
I have been using it, adding some libs and even contributing some changes. You should really give it a try!
For *nix based platforms Meson is now my go to build manager for c++ projects.
