CMake 2.8.11 also introduced generator expression +support in the target_link_libraries command. However, if an imported +target is linked as a result of a generator expression evaluation, the +entries in the 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 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 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 cmake_policy command to set it to OLD or NEW explicitly. + +.. include:: DEPRECATED.txt |
