We have a build server for our UE4 projects, which automatically compiles and packages the last version from SVN after each commit. All on and for Windows currently. Now we want to add Linux builds on that Windows build server as well.
In the UE4 wiki and on a few howtos on this topic I read that I have to compile the UE4 sources from GitHub. However, we are working solely with the official builds from Epic. Now for this crosschain compilations, do I really need to compile the engine, or can I also somehow use the pre-packaged UE4 versions?
