Can't deploy to Android ETC2 with UE4 source code build

Hey guys,

I have built UE4 from source code. Ever since I am not able to package for Android ETC2 anymore to deploy to GearVR.

Basically everything compiles, just before linking the final file I get a million undefined references and can’t find libary error messages, for example “cannot find -lgpg” and “cannot find -lphysX3Profile” and on goes the list.

I certainly have Android SDK 19 installed, and also setup everything according to the documentation, I have checked over and over again.

I am glad for any help!
