#target_sources(ser4cpp INTERFACE ${ser4cpp_public_headers})

Looks like people have gone round and round on this issue w/ no resolution:

Yes, that's exactly what I have found. The target_sources command can help by adding the sources to the consuming target, but it's not super nice in Visual Studio. What would have been cool is a target_sources with PRIVATE instead of INTERFACE, but it's not possible at the moment. I understand why, INTERFACE targets do not have a project created for them in Visual Studio, otherwise VS will complain that the project has nothing to build.

I left the sources list and this in comment. If a solution is ever found in CMake, it will be there. For now, it's not a big issue since it only affects the development experience on Visual Studio and probably XCode or some other IDEs. With CLion or with a basic text editor, the files are there.
