INSTALL_NAME_DIR ---------------- Directory name for installed targets on Apple platforms. ``INSTALL_NAME_DIR`` is a string specifying the directory portion of the "install_name" field of shared libraries on Apple platforms for installed targets. When not set, the default directory used is determined by :prop_tgt:`MACOSX_RPATH`. If the :prop_tgt:`BUILD_WITH_INSTALL_NAME_DIR` property is set, this will be used already in the build tree. Policies :policy:`CMP0068` and :policy:`CMP0042` are also relevant. This property is initialized by the value of the variable :variable:`CMAKE_INSTALL_NAME_DIR` if it is set when a target is created. This property supports :manual:`generator expressions `. In particular, the :genex:`$` generator expression can be used to set the directory relative to the install-time prefix. On platforms that support runtime paths (``RPATH``), refer to the :prop_tgt:`INSTALL_RPATH` target property. Under Windows, the :genex:`TARGET_RUNTIME_DLLS` generator expression is related.
