Using compiled UE to send to Oculus Quest (Missing files?)

Hi There

I have compiled UE4 and configured settings to work with oculus quest using the default VR level. I can play the level inside UE4 connected through the cable but I cannot seem to deploy the level to the headset.

The errors seemt to be “ID: cannot find -IGLESv2” as shown in the screen shot. Do I need an additional environment variable to make this work?

Thanks
