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

i have added all c++ source code from VehicleGame (4.5) to my own project.
now i am getting error for this line
#include “LandscapeInfo.generated.h”

which actually located here:
“Z:\UnrealEngine_4.6.1_Build\Engine\Intermediate\Build\Win64\Inc\Landscape\LandscapeInfo.generated.h”

how to point visual studio to that file ?

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

but i dont know what.

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