Subject: CMake: Fix macOS bundle wrapper generation

Now bundle wrapper scripts are created in the particular build folder,
i.e. in subdir 'Debug', 'Release' etc. in multi config builds (Xcode).
To do this, the scripts are now copied whenever the target is built
and not during the configuration phase.

To do: "install" wrapper scripts.
