How to build an ue4 from git source which can act like laucher downloaded

After we setup git ue4,we must re-build ue4 vcporject if we re-generate any uproject,but the ue4 source code is never changed!!We waste to do same thing again and again.

Someone suggests that we should use GUBP and gives out cmd line:
Engine\Build\BatchFiles\RunUAT.bat GUBP -Node=GatherRocket -TargetPlatforms=Win64 -NoDDC -CleanLocal -NoSign

But it didn’t work.Maybe just I don’t know how to make it works well without other else doc.So it didn’t work.

GUBP.ExecuteNode: System.IO.FileNotFoundException: Could not find file 'G:\UnrealEngine\4.13.2\Engine\Build\InstalledEngineFilters.ini'.

InstalledEngineFilters.ini is just in a laucher ue4 path not git-ue4 path!

Important
I don’t think we should pay more time to understand how the build tool work exactly if we just focus to implement cpp algorithm,rendering or some other game&engine module.

Do someone have anything good idea to get an easy way to build an utility git ue4?
