I don't know of any sure way of doing that, but if vcvarsall.bat is
located in the same relative place across all versions of VS then it
might be possible to sort of misuse some variable that CMake sets.

I had a quick look in one project I build with VS2010 and found one
candidate variable: CMAKE_LINKER.

  CMAKE_LINKER           = C:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin/link.exe
  vcvarsall.bat location = C:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/vcvarsall.bat

I'd consider that a terrible hack though, so hopefully there's someone
else with a better idea.

Beauty is more important in computing than anywhere else in technology
because software is so complicated. Beauty is the ultimate defence
against complexity.
