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 Interface:
|
|
set_property(TARGET tgt APPEND PROPERTY
|
|
COMPILE_DEFINITIONS_DEBUG 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>)
|
|
|
|
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 3.0.0. 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.
