This kind of works, even without the options, using just the simple

    using clang ;

and without setting up any MSVC build environment. clang++ finds MSVC 2017 
on its own.

But unfortunately any dynamic_cast use fails with

    undefined symbol: __imp___RTDynamicCast

regardless of whether I use -fuse-ld=lld. :-/
