Get avatar

Trying to get the avatar for the current player based on the online system and couldn’t find any functionality for it. However, I was trying to see if I could use the steam interface based off this post, but whenever I attempt to access SteamFriends/SteamUser/SteamUtils I get an error such as:

Error 1 error LNK2001: unresolved external symbol __imp_SteamUser C:\UE4.5\Engine\Intermediate\ProjectFiles\Controller.cpp.obj

Am I missing some header file somewhere, as intellisense seems to find SteamUser() easily enough.

Tried adding steam_api.h and other steam headers, along with the Subsystem interface for steam but couldn’t seem to stop this error? I feel like I could be missing something really obvious?

Still failing to find somewhere to get an avatar from for steam/xbox. Does this require and changes to the Engine code as I cannot find anywhere that supports this as of yet?
