I have a Unity3D project that uses SteamVR. Adding SteamVR support means adding 70MB of files to my project, and I don't want to check these in, as I think 70MB is way too much. I do want a reference checked in somewhere, as I am building in a CI pipeline.
For large binary assets I use Git LFS. As far as I know this doesn't work for an entire folder, only for files.
How can I somehow add this dependency (pinning my version) to Git, without tracking changes of 70MB of files?
