UE3 missing Physics file

I trying compile source code of UE3 which I found on Github.
It has already Sln proj file which is compatible with VS2008/2009.
So before build Engine I make some changes with
configuration type, but the problem is I can’t switch to the Win64 platform.
Anyway it generated Object file from source after build, I don’t know why but I selected as windows application (.exe)
So I repeat the build solution, and it failed because I missing libpng.lib.
