Thanks, finally. Olaf, do you see how simple it is? And this code could be shortened by a mile:

if(MSVC90)
  set(comp_suffix _2008)
elseif(MSVC80)
  set(comp_suffix _2005)
elseif(MSVC71)
  set(comp_suffix _2003)
elseif(MSVC70)
  set(comp_suffix _2002)
elseif(MSVC60)
  set(comp_suffix _vc6)
endif()
set(arch_suffix)
if(CMAKE_SIZEOF_VOID_P EQUAL 8)
  set(arch_suffix _x64)
  # THIS IS SPECIFIC TO JOHN'S PROJECT
  if(DETECT_64BIT_PORTABILITY)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /Wp64")
  endif()
endif()
set(CMAKE_DEBUG_POSTFIX          _d${comp_suffix}${arch_suffix})
set(CMAKE_RELEASE_POSTFIX          ${comp_suffix}${arch_suffix})
set(CMAKE_RELWITHDEBINFO_POSTFIX   ${comp_suffix}${arch_suffix})
set(CMAKE_MINSIZEREL_POSTFIX       ${comp_suffix}${arch_suffix})

You can extend this to your hearts content...
