CMake 2.8.11 also introduced generator expression +support in the :command:`target_link_libraries` command. However, if an +imported target is linked as a result of a generator expression evaluation, the +entries in the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of that target were not +checked for existence as they should be. + +The ``OLD`` behavior of this policy is to report a warning if an entry in +the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of a generator-expression +conditionally linked ``IMPORTED`` target does not exist. + +The ``NEW`` behavior of this policy is to report an error if an entry in +the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of a generator-expression +conditionally linked ``IMPORTED`` target does not exist. + +This policy was introduced in CMake version 3.0. CMake version +|release| warns when the policy is not set and uses ``OLD`` behavior. Use +the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. + +.. include:: DEPRECATED.txt |
