Fixing the Vehicle class in UE4 starting with NWheel implementation.

Hi,! I have troubles when I try to use VehicleMovementComponentNW to inheritance the class WheeledVehicleMovementComponent in VS2015. The edition number of the Engine is 4.12.2.
When I use the code #include “PxVehicleDriveNW.h” in VehicleMovementComponentNW.cpp, my VS2015 always says"fatal error C1083: “PxVehicleDriveNW.h”: No such file or directory". But when I use the full directory #include “D:/Epic Games/4.12/Engine/Source/ThirdParty/PhysX/PhysX-3.3/include/vehicle/PxVehicleDriveNW.h” instead of #include “PxVehicleDriveNW.h”, it still doesn’t work! It seems that my project cannot recognize the path of some souce code.
Could you help me and tell me how to solve this problem, please?
