| ------- |
| |
| Conditionally linked imported targets with missing include directories. |
| |
| CMake 2.8.11 introduced introduced the concept of |
| :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`, and a check at cmake time that the |
| entries in the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of an ``IMPORTED`` |
| target actually exist. 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. |
