How to do proper Rocket build from source distribution?

This quesion bumps from time to time, but there seems to be no ansfer for this,
assumming I’v pulled new unreal source distribution from /promoted branch (and integrate some modifications inside renderer/vr),
How should I proceed to do Rocked build of it ?
(to distribute among other (non-coding) team members just the engine, with the ability to do -rocket c++ builds).

Any working tutorial would be nice :slight_smile:

For now I’v don this simply by compiling ‘Development editor’ from VS2013, then coping all the stuff (without some parts of Intermediate directory) and just removed SourceDistribution.txt, then this fake rocket build worked fine, but after
last pull from promoted things changed and with this method now I’m getting:

Use of -rocket argument on command-line to test Rocket behavior is deprecated, please ensure that you’ve built a true Rocket build.
Discovering modules, targets and source code for game…
UnrealBuildTool Exception: ERROR: GetBuildPlatform: No BuildPlatform found for Win64

so how to do TRUE ROCKET BUILD then ?
