Slicer build failed in windows 10, numpy patch problem

Dear all,
I am trying to build a release type build of Slicer -r 26489 source code in windows 10 using visual studio 2013 update 5.
The build fail because of Numpy. I got this error when I try to build numpy:

note: The debug build was successful but I had to disable SimpleITK.
Thanks for your input.
