Can you suggest where those artifacts should be stored?

I often have projects that require third party libraries, and perhaps I change or upgrade the version of the library I use during the history of my project. I would like to have everything versioned together so if I check out a certain commit, I know that everything will work.

The downside of this is that my git repo will get bloated over time if I keep changing large dlls. I've sometimes made submodules to mitigate this problem. Git lfs also seemed like a good solution, but your comment makes me feel like I'm doing something bad here...
