These are some engine files missing…I got the 4.9.2-release version from github.
Bump? 
Ah god where can i get these files and why aren’t these already there?
I remember to have copied missing files from Windows, but I’m pretty sure there’s now a *.sh to get those files in 4.10.2
I’ve properly setted up the engine and built everything several times.
There was a need to rerun setup.bat in order to grab the extra dependencies (initially, the toolchain was not downloaded).
