Visual Studio itself does not have compiler selection in the same sense 
as is available with e.g. Makefiles or Ninja.
It can not be directly told to use specific compiler paths (you will not 
find any compiler paths in the generated solutions/projects).

It does support "Platform Toolset"s which in manually created projects 
can be set/seen in the "General" project settings and in CMake generated 
projects can be set via the -T option [1].

I'd stick to Ninja or Makefiles for cross-compiles unless you are 
targeting something with pre-existing toolset support.
I think e.g. Android is supported via CMAKE_SYSTEM_NAME "Android" and 
NVIDIA Nsight Tegra integration [2].
