1.. note:: 2 A call to :command:`target_link_libraries(<target> ...)` may update this 3 property on ``<target>``. If ``<target>`` was not created in the same 4 directory as the call then :command:`target_link_libraries` will wrap each 5 entry with the form ``::@(directory-id);...;::@``, where the ``::@`` is 6 literal and the ``(directory-id)`` is unspecified. 7 This tells the generators that the named libraries must be looked up in 8 the scope of the caller rather than in the scope in which the 9 ``<target>`` was created. Valid directory ids are stripped on export 10 by the :command:`install(EXPORT)` and :command:`export` commands. 11
