Cake build fails if only Visual Studio 2017 installed

[rprouse]

I am working on a new computer with only Visual Studio 2017 installed. I can build the solution fine in Visual Studio, but when I try to build using Cake, I get the error,

========================================
Build45

An error occured when executing task 'Build45'.

I am using Visual Studio 2017 15.2 (26430.6) release.

Does where.exe MSBuild* give you multiple paths? Or just the folder under the VS2017 install directory?

Upgrading to a newer version of Cake fixes it for me. PR coming...

With the new Cake, the build engine version is different,
