When I use CPack to create a ZIP archive of a project on Windows, it includes the system .dll dependencies. However, when I do it on macOS (using g++ from brew), it does not include any system deps, only the executable. I’ve tried to create a minimal example here: [GitHub - rheiland/cpack\_test](https://github.com/rheiland/cpack_test)

Recent macOS releases have “hidden” the actual libraries in some binary cache somewhere. You can see that the SDK doesn’t actually contain `.dylib` files, but instead `.tbd` stub files that indicate where in the cache to look. In short, there _aren’t_ system libraries to copy. Instead, I would recommend you set your macOS target deployment version low enough and trust that Apple continues to make that work.

Thanks for the reply. The fact that I’m using g++ SDK from brew (in order to get OpenMP) would seem to complicate things, unless I’m missing the point.

Oh. I don’t know if HomeBrew libraries are considered “system” by the `InstallRequiredSystemLibraries` module. They might not be. I would recommend looking into [`file(GET_RUNTIME_DEPENDENCIES)`](https://cmake.org/cmake/help/latest/command/file.html#get-runtime-dependencies).
