error LNK2001: unresolved external symbol "private: static class FName const UE::AnimationWarping::FRootOffsetProvider::TypeName"

I looked in unreal code. I think I need to include declaration of AnimationWarping namespace. I see that it has been defined in AnimationWarpingRuntimeModule.cpp but I can’t find which header file it is declared in (I have searched online and in unreal code installed on my PC). Would really appreciate if someone can point me in the right direction.
