udpating cmake stuff  to compile in windows.. we'll be bouncing back and forth like this for  a little bit between platforms, making sure one cmake setup works for everything
Removed build of  ICECACHE for now (need to remove from  maya plugin as well)  since it needs work to be cross plat compatible
Haven't finished  updating all the cmake stuff yet for windows .. need to do  maya plugin and eventually add support for arnold and houdini plugs
