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