I had the same problem when trying to add the plugin to my C++ project (it worked fine in blueprints). Struggled with this for about a day and it is finally working. I think the main problem for me was that “ATL” was missing.
There is a path in the ZipUtility.Build.CS file that reads:
“C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.14.26428/atlmfc”
But I had no such folder. I solved it by opening the Visual Studio Installer, clicking “more” and “modify”. I then installed the “Desktop development with C++”-package which includes ATL. Now the folder appeared and I could compile.
