Hairworks UE Source Code:Error C2027: use of undefined type 'UAssetImportData'

I am trying to compile the Github Hairworks UE source code
i followed all the instructions problem is it gives me some errors tried with VS 2013 and 2015
but sadly nothing will work searched all over for a sollutions without success :frowning:
extracted the zip file again and again from the begining download all the files from the setup. file
and always gives me this erros

Error C2027: use of undefined type 'UAssetImportData'

Error C3861: 'StaticClass': identifier not found	c:\unrealengine-hairworks\engine\source\runtime\coreuobject\public\uobject\UObjectGlobals.h

Error : Failed to produce item: C:\UnrealEngine-HairWorks\Engine\Binaries\Win64\UE4Editor-Engine.dll	C:\UnrealEngine-HairWorks\Engine\Intermediate\ProjectFiles\

When i try the pure UE source code from Github it builds and runs with no problems its just the Hairworks version
that i need and i just cant figure it out
Please any advice or solutions ?
would really really apreciate it a lot !!! Im sorta new to running the engine this way but i really need hairworks in my project. :confused:
Thanks a lot !!

Iā€™m also having trouble with this. Gives me the exact same error when I build.

Hi ShotgunHR
I resolved this error with the help from niexuchina from GitHub.
In HairWorksAsset.cpp, try to include EditorFramework/AssetImportData.h.
This worked for me the only problem i have now are the reflections i guess , when i import a light source i get this weird rgb colors of the hair when the reflections kick in dunno why this happens still trying to figure this out .

Thank you! This fixed it for me!
