This is the “terrible rpath” issue on macOS. The library says “you need to use rpath to use me” (with the `@rpath/` library id), but nothing says what path to actually add. Here, you’ll need to do it manually. See [how CI does it](https://gitlab.kitware.com/vtk/vtk/-/blob/cf341212cdd0989c9ac19ffc1f77a7d24eaeb02a/.gitlab/ci/configure_macos.cmake#L25-27).

I have discussed it in the CMake Discourse before (and maybe even an issue), but libraries will need an `IMPORTED_RPATH` property to be set so that CMake can know to add the right `-Wl,-rpath,` flags to the linker.
