3DEXCITE_DELTAGEN_2025x_RF2_SDK - cannot get sample to build

I installed VSCode 2017 as per the documentation and got Qt5.6.2 to install. I copied one of the example widgets and followed instructions to (1)Clone Simple Widget, (2)Adapt Clone's Project File, (3)Create a Solution File, (4)Adapt Root Directory, (5)Adapt Header File, (6)Check Plugin ID, and (7)Adapt Header File. At this point, the documentation says I have successfully cloned a smaple plug-in into an independent self contained plug-in solution, but when I build the solution, I get the following errors:
