ERROR: UBT ERROR: Failed to produce item: UE4Editor-UPupilLabsVR.dll

Hey guys,
I am new into UE. Iam trying to connect UE to the VR-Eye-Tracker from PupilLabs using zeroMQ.

I found this plugin GitHub - SysOverdrive/UPupilLabsVR: Plugin for connecting to Pupil Labs VR using the ZeroMQ library with an Unreal Editor Module which I tried to build into the engine.
With this command:
.\RunUAT.bat BuildPlugin -plugin=“C:\Users\VR\Documents\UnrealProjects\Plugins\UPupilLabsVR/UPupilLabsVR.uplugin” -package="C:\Users\VR\Documents\UnrealProjects\HelloWorld\PL_Packaged"

I always get this Error message:
UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: C:\Users\VR\Documents\UnrealProjects\HelloWorld\PL_Packaged\HostProject\Plugins\UPupilLabsVR\Binaries\Win64\UE4Editor-UPupilLabsVR.dll

I hope you can help me.

I fgured it out my problem was not exactly causded by producing UE4Editor-.dll.
My API was missing this parameter InStackSize btw. its zero.

**InStackSize The size of the stack to create. 0 means use the current thread’s stack size **

Thread = FRunnableThread::Create(this, TEXT(“PupilMsgWorker”), InStackSize, TPri_AboveNormal);
