gz3doom

Not a pull request because I have only tried it for 2 minutes and saw it's working in the steamvr compositor, but haven't tried setting up controllers.

Recent reddit thread about the openvr fork https://www.reddit.com/r/SteamVR/comments/8q12au/doom_vr_with_motion_controls/

Repo is at https://github.com/Fishbiter/gz3doom

Compiling worked out of the box for me:

cmake .
make -j$(nproc)
./gzdoom
