[ITK] Win64 SimpleITK build error: NMAKE : fatal error U1095 (command line too long)

[Bradley Lowekamp]

Hello,

What version of CMake and Visual Studio are you using?

What is your build and source path?

Also know which Super build target that's causing the problem would be helpful too.

Try have having your build and your source in a really short paths like "C:/b/SimpleITK" and "C:/b/bld".
