[CMake] How to add files to Visual Studio 'Utility' project

[J. Caleb Wherry]

Yes, I understand that. The error message is pretty clear.

My main question is really why is that the case? In VS, there is no
restriction to adding files to a utility project. So why does CMake have
this restriction?

I assume it is because it is generator specific and there isn’t a clean way
to implement add_custom_target across all of them. In that case I would
expect some special case handling for generators that do support it.

And it’s not like CMake can’t add files to that Utility project, because it
does: it adds the Java rules files. It just doesn’t allow the user the do
the same. It’s a restriction that doesn’t really make sense to me.
