Yes, but only for the existing VS 11 WinCE-specific generator names.

It is an internal implementation detail of the WinCE-specific
VS generators.

Yes.

Let's use a name specific to WindowsCE like "CMAKE_VS_WINCE_SDK",
at least for discussion and review purposes, so I can see where
the variable fits in to the generator with your changes. Then
we can decide if there is a more general name to be used later.

The CMAKE_GENERATOR_TOOLSET is where a user-specified choice is
set/saved. The CMAKE_VS_PLATFORM_TOOLSET is the actual toolset
that the generator will write in to the project file, and is
provided only for reference (and internal compiler id detection).
The latter may be set to a default selection that CMake VS gens
pick even when no explicit CMAKE_GENERATOR_TOOLSET is set.

I'm not familiar enough with VS+WinCE tools to know how independent
they are.
