Can't Package game with FJsonObjectConverter

It is not possible to package a game when using the FJsonObjectConverter.

This Converter is part of "JsonUtilities", and whenever I'm including this to my Build.cs as follows, the packaging fails:

PublicDependencyModuleNames.AddRange(new string[]

{ "Json", "JsonUtilities" }

);
The Error Message when packaging is:

MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: LINK : fatal error LNK1181: cannot open input file 'F:\Unreal Engine Launcher\Unreal Engine\4.9\Engine\Binaries\Win64\UE4-JsonUtilities.lib'
As someone posted here, building the engine from source seems to solve this problem. This is no option for me, though.

We need the FJsonObjectConverter to convert a Json string to UStruct.
