STEP：  
git clone [GitHub - dev-cafe/cmake-cookbook: CMake Cookbook recipes.](https://github.com/dev-cafe/cmake-cookbook/)

It doesn’t appear as though the example you’re referring to is set up to use CPack properly. I would recommend asking the author(s) of that project to clarify documentation.

Thanks for your advance.  
Do you have the simple sample with cpack (macOS .dmg)?  
My subject is create a .dmg and install it with interface.

I don’t have a simple one off hand, sorry. I do know you should use `add_executable(MACOSX_BUNDLE)`, use `include(CPack)`, and set a bunch of `CPACK_` settings at least. Those might help you find other examples on GitHub or such. Others here may have better information as well.
