New VTK build on windows - doesnt build anything

Followed instructions here:
https://vtk.org/Wiki/VTK/Building/Windows

I am using Visual Studio 2019.

CMake 3.15.3

CMake “configures” and “generates”.

Produces a VTK.sln

Load VTK.sln into VS19 - issue build.

Get nothing.

The problem was with CMake.

I tried to use C:[UTILITIES] as my root install directory.

Evidently CMake cannot handle Brackets “[” in file paths.

Go figure!
