OpenVR is great because it's at least partially headset-agnostic. And of course is the path to SteamVR/Lighthouse-based hardware. Sadly, the official OpenVR library is C++ with no apparent official C bindings.

So, it will be necessary to:

1. Find/build C bindings for the OpenVR C++ API
2. Reconcile the OpenVR API with rovr and decide whether SteamVR support should be here or in a parallel library
3. Add input support, at least for Lighthouse-based SteamVR controllers (and maybe Hydra while we're at it?)

Hmd doesn't expose enough metadata to allow another windowing library to find the Oculus monitor and create the window in the appropriate place. It needs to expose both the native monitor ID and window size/position information reported by the Oculus SDK to deal with window positioning across all platforms.

This was a somewhat big update, so I'd like to put some thought into how to expose the compositor (and how this might affect the usefulness of including OpenVR support in this library vs. elsewhere).

I cannot get a build to complete.

Could not compilewayland-client.

I get the same errors for stable/beta/nightly under Linux x86_64.

Unlike OS X/Windows, there's no identifier for the display given by the Oculus SDK. So position information needs to be used to guess which display is the Hmd. glutin doesn't currently expose enough information to perform this match.

The move to an official shared-DLL support model leaves two options:

• Build against the installed runtime version of the DLL; no SDK build required.
• Continue to build against SDK source.

Building against the source removes an installation dependency for dev. But given Oculus' intended deployment model, there's no other real advantage to building against a private copy of the SDK.
