Useing a plugin in ue4

Hello,

On YouTube some one posted a zip file with the plugin code from de gdc of ue4 about fluid simulation and other things.
you can find it herehttps://cdn.unrealengine.com/gdc/ShaderBits-GDC-Pack.zip
But I can not get the plugin working in ue4.
What must I do to get this working in ue4?

Thanks
