Hello.  
I am trying to compile 4.16 branch from commit  
SHA-1: 6e7549f50d662b3ee4328c304ef082c7578be90a

- Fix fontrender automation test failure

#jira UE-45230  
#rb none

[CL 3450190 by Marcus Wassmer in 4.16 branch]

But this branch couldn’t be compiled because of

I’ve got the same error trying to recompile UE4 to modify SceneCapturer.cpp for the Stereoscopic 360 plugin.
