Qt 5 cmake fails with undefined reference to vtable on hello world with inc & src as subdirs

Question

Update 2

After messing around a bit (and some editing of the generated Makefiles), it looks like what is happening is that moc is not properly processing Mai

Answer 1

I had the same problem and found a solution. As Eric Lemanissier commented in an issue on GitHub:

This error is not related to conan: you need to add your header files in add_executable, otherwise the moc won't parse them

The header files have to be added to the project using an add_executable or add_library statement. If this is not done, automoc won't parse the files.
