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 .
