Control Rig

I want to create my own Control Rig in C++. However, I’m unable to build the project. I’m getting the following error:

unresolved external symbol "__declspec(dllimport) public: __cdecl UControlRig::UControlRig(void)" (__imp_??0UControlRig@@QEAA@XZ) referenced in function "void __cdecl InternalConstructor<class UCustomControlRig>(class FObjectInitializer const &)" (??$InternalConstructor@VUCustomControlRig@@@@YAXAEBVFObjectInitializer@@@Z)

I’ve added the modules to my project:

PublicDependencyModuleNames.AddRange(new string[] {  
   ...
   "ControlRig",
   "RigVM"
});

My ih__CustomControlRig.h

#pragma once

#include "ControlRig.h"
#include "ih__CustomControlRig.generated.h"

UCLASS(BlueprintType)
class UCustomControlRig : public UControlRig
{
    
	GENERATED_BODY()
	
};
