undefined reference to FHttpModule::Get()

Can some1 help me out?
#include “Runtime/Online/HTTP/Public/Http.h”
TSharedRef < IHttpRequest > HttpRequest = FHttpModule::Get().CreateRequest();
CompilerResultsLog: /home/nikolai/Dokumente/Unreal Projects/TP_Android_Test/Source/TP_Android_Test/BFL_ServerCom.cpp:33: undefined reference to `FHttpModule::Get()’

I just rebuild unreal engine, but it was no help
Reinstalled NvidiaCodeWorks for Android: No Help

setup another project and added code: No Help

The linker seems not to know, to link the FHTTPModule … I’m using visual studio code … atm i dont know how to configure it …

Fixed this with adding the module to *.uproject-file

I want to add to this topic, that somehow those logs are marked as CompilerLogs, what is very confusing, the Compiler will never complain about missing references…
The Linker does.
