Generate Procedural Mesh

Right now i have some progress. According to this wiki pagei make it work. But one problem now - Intelli Sense in VS cant find this includes. Also i cant find any api documentation, where i can check how to call all of this functions.
I found some header files in folder. There was one more cool file called “KismetProceduralMeshLibrary.h” inside of this file i found one cool function that generates tangents and normals. I want use it but i cant, cause i dont know what to #include, in my .h file.
So, main quastion is - how to include it properly, to be everything work as it should. I whant intelisense understand my includes, not only build system.
