| |
| Fatal error on relative paths in INCLUDE_DIRECTORIES target property. |
| |
| CMake 2.8.10.2 and lower allowed the 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 |
| 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 cmake_policy command to set it to OLD or NEW explicitly. |
