[Solved] Not being able to "Build and Run" for the Oculus Go in 2018.2.6f1

[fariazz]

Are people being able to run their projects in a connected Oculus Go using Unity 2018.2.6f1?

I keep on getting this error. Have reinstalled Android SDK, Android NDK, Java SDK, using recommended build settings, restarted the computer and the Library folder of the project. I can build but not "build & run". Error is about this "GL/glew.h" file not found.. really strange.

It turns out I had an older version of the Oculus Avatar SDK in my project, which was causing this error.
