How do i build for direct to rift?

Hello Community, hope everyone's doing great, I'm tried building a scene for oculus rift , I'm using oculus 0.7 sdk, in my scene i have only OvrCameraRig asset from oculus utilities package, when i build the scene the oculus seems to be off with orange light turned on, nothing shows up on lenses, I tried building with virtual reality support turned on and off both,nothing seemed to work, plus my rift is not detected as a second monitor , i can't run it in extended mode . How do i build for oculus?
