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

Fri Aug 14 10:30:48 EDT 2015

Thanks Andras for the tip about CMAKE_CACHE_ARGS and to Brad for the tip about Ninja. I doubt that this is the last time I’ll run into problems with overly-long command lines on Windows so it’s nice to have a variety of techniques to deal with the problem in the future.

Cheers
Philip
