| Ignore COMPILE_DEFINITIONS_<Config> properties |
| |
| CMake 2.8.12 and lower allowed setting the |
| :prop_tgt:`COMPILE_DEFINITIONS_<CONFIG>` target property and |
| :prop_dir:`COMPILE_DEFINITIONS_<CONFIG>` directory property to apply |
| configuration-specific compile definitions. |
| |
| Since CMake 2.8.10, the :prop_tgt:`COMPILE_DEFINITIONS` property has supported |
| :manual:`generator expressions <cmake-generator-expressions(7)>` for setting |
| configuration-dependent content. The continued existence of the suffixed |
| variables is redundant, and causes a maintenance burden. Population of the |
| :prop_tgt:`COMPILE_DEFINITIONS_DEBUG <COMPILE_DEFINITIONS_<CONFIG>>` property |
| may be replaced with a population of :prop_tgt:`COMPILE_DEFINITIONS` directly |
| or via :command:`target_compile_definitions`: |
| |
| .. code-block:: cmake |
| |
| # Old Interfaces: |
| set_property(TARGET tgt APPEND PROPERTY |
| COMPILE_DEFINITIONS_DEBUG DEBUG_MODE |
| ) |
| set_property(DIRECTORY APPEND PROPERTY |
| COMPILE_DEFINITIONS_DEBUG DIR_DEBUG_MODE |
| ) |
| |
| # New Interfaces: |
| set_property(TARGET tgt APPEND PROPERTY |
| COMPILE_DEFINITIONS $<$<CONFIG:Debug>:DEBUG_MODE> |
| ) |
| target_compile_definitions(tgt PRIVATE $<$<CONFIG:Debug>:DEBUG_MODE>) |
| set_property(DIRECTORY APPEND PROPERTY |
| COMPILE_DEFINITIONS $<$<CONFIG:Debug>:DIR_DEBUG_MODE> |
| ) |
| |
| The ``OLD`` behavior for this policy is to consume the content of the suffixed |
| :prop_tgt:`COMPILE_DEFINITIONS_<CONFIG>` target property when generating the |
| compilation command. The ``NEW`` behavior for this policy is to ignore the content |
| of the :prop_tgt:`COMPILE_DEFINITIONS_<CONFIG>` target property . |
| |
| 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 :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. |
