Xcode 15, which provides the compiler toolchain for building libvirt on macOS has switched to a new linker that warns about duplicated "-lblah" options on the ld commandline. In practice this is impossible to prevent in a large project, and also harmless.
Fortunately the new ld command also has an option, -no_warn_duplicate_libraries, that supresses this harmless/pointless warning, meson has a simple way to check if that option is supported, and libvirt's meson.build files already have examples of adding an option to the ld commandline if it's available.
