title: CMake 64bit windows generator not working
body: <p>I wish to generate a x64 project for Visual Studio with cmake. Unfortunately, cmake always generates x86 projects. The generator name I use is "Visual Studio 12 Win64". cmake is run from x64 VS developer console, yet still projects are generated for x86 and CMAKE_SIZEOF_VOID_P is always 4, not 8. There are no errors during project generation. Could this be a bug in cmake?</p>
