Building on Win32 doesn't imply that you'll have the required header; it currently needs to be installed [[ https://blogs.msdn.microsoft.com/heaths/2016/09/15/changes-to-visual-studio-15-setup/ | separately ]] via nuget. While it would be possible to have cmake create a packages.config file when configuring a visual studio project, the API is only at the RC stage and so the distribution method could potentially change between now and the Visual Studio 2017 release (even if that's not a concern, it's probably out of the scope of this patch anyway).
Although the code looks useless sitting there ifdefed out, it could be useful for someone eager enough to get the package themselves and run a custom Clang build.
In the meantime, Visual Studio 2017 installations can only be detected when running in the correct developer command prompt, or by putting one of its toolchain's bin directories at the top of PATH.
