| |
| Fatal error on relative paths in :prop_tgt:`INCLUDE_DIRECTORIES` target |
| property. |
| |
| CMake 2.8.10.2 and lower allowed the :prop_tgt:`INCLUDE_DIRECTORIES` target |
| property to contain relative paths. The base path for such relative |
| entries is not well defined. CMake 2.8.12 issues a ``FATAL_ERROR`` if the |
| :prop_tgt:`INCLUDE_DIRECTORIES` property contains a relative path. |
| |
| The ``OLD`` behavior for this policy is not to warn about relative paths |
| in the ``INCLUDE_DIRECTORIES`` target property. The ``NEW`` behavior for this |
| policy is to issue a ``FATAL_ERROR`` if ``INCLUDE_DIRECTORIES`` contains a |
| relative path. |
| |
| This policy was introduced in CMake version 2.8.12. 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. |
