For XCode 15, the dyld linker behaviour changed and

no longer automatically falls back to checking
the contents of /usr/local/lib when trying to
evaluate an @rpath dependency. As a result,
runtime linking is failing on up-to-date MacOS
systems. The INSTALL_NAME_DIR directive is used
for APPLE builds, to ensure that the installed
library advertises its install path, so libraries
that link to it can find it again when dynamic
linking time arrives.
