On Windows it is only supported when using the Visual Studio >= 10 
Generators.
In that context the Toolset is the PlatformToolset which is a feature of 
MSBuild.
I don't think that concept is transferable to nmake/jom.

In case of nmake/jom the compiler setup depends on information provided 
by the environment.
Which is why cmake has to be run from the compiler command line 
environments when using these generators.

There does not seem to be a command line environment for v110_xp 
provided by visual studio itself but there are instructions on how to 
set one up here (jump to "Targeting from the Command Line"):

I haven't tested these myself.
