It works fine if I close cmd and re-open it. It seems building with VS2015 leaves some bad variables.

@seishun it's an edge case with a simple workaround (as you stated), but I'll see if there's a simple solution.

Fix: #13485

[DudnykOleksandr]

It appeared to me, that the reason for the problem was a not needed VCTargetsPath system variable. After removing it, VS 2017 now sees V141 toolset.
I had VS 2017 Community first, maybe that made the problem.
