Did it for decades before Docker was a thing. Even for projects with lots of complex dependencies, some tied into the OS. Basically you just need a well documented, thorough and up to date set of steps for setting up the environment.

This is something you should still have even if using Docker.

I don't knock Docker for making that easy and "tied up with a bow and ribbon" for its users (that's great!), but do agree there are times when you really don't need the extra abstraction layer.
