According to https://bugs.freedesktop.org/show_bug.cgi?id=105366,
libuuid is provided as part of libsystem_c. The Apple libsystem_c
library cannot be linked to directly using an absolute path; doing so
will cause the linker to throw an error 'cannot link directly with
/usr/lib/system/libsystem_c.dylib' and the linker will suggest linking
with System.framework instead. Linking to this framework is equivalent
to linking with libSystem.dylib, which can be confirmed on a macOS
system by executing at a terminal the command `ls -l
/System/Library/Frameworks/System.Framework` -- the file "System" is a
symlink to `/usr/lib/libSystem.B.dylib`, and `/usr/lib/libSystem.dylib`
also symlinks to this file. Running `otool -L /usr/lib/libSystem.dylib`
confirms that it will link dynamically to
`/usr/lib/system/libsystem_c.dylib`."""
