How to point visual studio to "LandscapeInfo.generated.h"?

i have added all c++ source code from VehicleGame (4.5) to my own project.

#include “LandscapeInfo.generated.h”

which actually located here:

how to point visual studio to that file ?

most probably i have to add something to “…build.cs”.

but i dont know what.

after adding this one to build.cs:
PublicDependencyModuleNames.AddRange(new string[] { “Landscape”});
