I am not sure why you would need –DCMAKE_HOST_UNIX at all – I have never needed it. My current system is Windows 7 with Cygwin 64-bits, so that is definitely not the same as your Windows XP system. That makes it a trifle complex to try and reproduce that part of your problem. I will stare at the output you attached and see if I can find the cause, as well as try whether the makefile problem occurs on my system.
