LINK LIBRARIES INDIRECTION

.. 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 wrap each entry with the form ::@(directory-id);...;::@, where the ::@ is literal 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.
