    ARcore development HelloARUnreal 4.20

    after some difficult time setting up the environment so I can try the Hello World ARcore I am unable to run it. Skipping all the tedious task and monstrous size of the 60+ gigs repository to build UE4-20 with arcore sdk 1.5. Went "almost" as it was in Quickstart guide (took me about 10 hours but ok).

    After all this the Project Packaging as for Android -> ASTC as suggested I am encountering this issue:

    UATHelper: Packaging (Android (ASTC)):   Building 1 action with 4 processes...
    UATHelper: Packaging (Android (ASTC)):     [1/1]
    UATHelper: Packaging (Android (ASTC)):     D:\Unreal\UnrealEngine\Engine\Plugins\Runtime\GoogleARCore\Source\GoogleARCoreBase\Private/GoogleARCoreAPI.cpp:307: error: undefined reference to 'ArConfig_setFocusMode'

    I have cloned the arcore-unreal-sdk with the examples and imported the HelloARUnreal 4.20 which made a copy from which I am trying to build up the HelloARUnreal.

    Any tips on what went wrong?
