You could argue that Bazel, Nix and Guix solve that problem but they introduce a lot of complexity as a result because it's not a simple abstraction. Hell, you could probably pull it off somehow in Cmake if you placed no value on your sanity. Most standard lib package managers double up as build tools for bundling your code after all. It's a totally different problem space than the one asdf aims to solve, which is just managing multiple independent versions of some programming language binaries in a consistent way, so you're not dancing between nvm, rvm/rbenv/chruby, virtualenv, etc. etc.
