Setting CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_PROCESSOR is often enough for CMake to handle cross-compilation even without a toolchain file, but it gets in the way of generators that handle cross-compilation on their own (in Visual Studio's case, using the -T "toolset" option).

There was a problem hiding this comment.
This is definitely weirdly complicated for an inline condition, and depends on the default generator choice for MSVC being Visual Studio (implemented below, unchanged). Suggestions welcome on how to reorganize this.

CMAKE_SYSTEM_NAMEandCMAKE_SYSTEM_PROCESSORis often enough for CMake to handle cross-compilation even without a toolchain file, but it gets in the way of generators that handle cross-compilation on their own (in Visual Studio's case, using the -T "toolset" option).Narrow fix for the issue I brought up in #158 (comment). Possible fix for #171 as well, if it does turn out to be the same thing.
