Compilation Error Alert EditorVR requires at least one partner (e.g. Oculus, Vive) SDK to be install

I'm trying the tool from the blog:

EDITORVR EXPERIMENTAL BUILD AVAILABLE TODAY
https://blogs.unity3d.com/2016/12/15/editorvr-experimental-build-available-today/

And I get an alert:

What to do? From where I can download this dll or SDK? This are drivers?
And how to install them: Just drag and drop into the project asset folder?

 

The step you are missing is that you need to have Oculus Utilities or the SteamVR plugin in your project, but you should review this doc just in case (which is linked from the blog post you mentioned), especially the "Downloading EditorVR" and "How To Add EVR to Your Project" sections.
