[CMake] solution for 64-bit platform

[Hugo Gratama van Andel]

Dear CMake users,
I am trying to compile ITK for windows XP 64-bit with the Visual Studio 
2005 Beta. One very annoying problem is that the created solution by 
CMake defaults to the win32 platform in stead of the x64 that I need. 
Visual Studio 2005 needs aprox. one hour to change the settings for the 
whole project (probably due to a bug). Can I specify the desired 
platform somewhere in the CMakeLists.txt?
thanks in advance,
