Any os-level package manager. Also: "npm -g", "pip install", "cargo install", etc.. Lots of programming languages or build systems will look for dependencies in globally-known locations. Other than cargo, python's virtualenv, node_modules, and some other modern languages/systems I would imagine most are not project-scoped. Go had a single global dependency tree until go.mod, etc...
