Missing headers for Android target?

Hello I’m trying to follow tutorials and build an Android package using the git-master on GNU/Linux but getting Oculus-related build errors:

[2019.10.23-14.32.26:408][646]PackagingResults: Error: no type named ‘FPose’ in namespace ‘OculusHMD’
[2019.10.23-14.32.26:408][646]PackagingResults: Error: use of undeclared identifier ‘FPose’
[2019.10.23-14.32.26:408][646]PackagingResults: Error: use of undeclared identifier ‘ToOvrpNode’
[2019.10.23-14.32.26:408][646]PackagingResults: Error: use of undeclared identifier ‘ovrp_GetNodePresent2’

I think some Oculus headers are missing, or not being included by the build system - should they be included with the Engine or do I need to install them manually/separately?

I’m not actually trying to build for Oculus (just trying to follow basic tutorials still), can I disable the Oculus features/support somehow?
