Seems to work correctly from my tests:
CMakeLists.txt:
cmake_minimum_required (VERSION 2.8)
project(test CXX)
message( STATUS "CMAKE_GENERATOR: ${CMAKE_GENERATOR}")
message( STATUS "CMAKE_CL_64: ${CMAKE_CL_64}")
c:\dev2\Builds\test\x64>cmake -G "Visual Studio 8 2005" ../.

IIRC that doesn't work if you use the Studio generator (i.e. not
Makefiles). So
this needs to be something like "if (CMAKE_CL_64 or CMAKE_GENERATOR
MATCHES
