| .. note:: | |
| A call to :command:`target_link_libraries(<target> ...)` may update this | |
| property on ``<target>``. If ``<target>`` was not created in the same | |
| directory as the call then :command:`target_link_libraries` will add a | |
| suffix of the form ``::@<directory-id>`` to each entry, where the | |
| ``::@`` is a separator and the ``<directory-id>`` is unspecified. | |
| This tells the generators that the named libraries must be looked up in | |
| the scope of the caller rather than in the scope in which the | |
| ``<target>`` was created. Valid directory ids are stripped on export | |
| by the :command:`install(EXPORT)` and :command:`export` commands. |
