Ignore COMPILE_DEFINITIONS_<Config> properties
CMake 2.8.12 and lower allowed setting the
COMPILE_DEFINITIONS_<CONFIG>
target property and
COMPILE_DEFINITIONS_<CONFIG>
directory property to apply
configuration-specific compile definitions.
Since CMake 2.8.10, the COMPILE_DEFINITIONS
property has supported
generator expressions
for setting
configuration-dependent content. The continued existence of the suffixed
variables is redundant, and causes a maintenance burden. Population of the
COMPILE_DEFINITIONS_DEBUG
property
may be replaced with a population of COMPILE_DEFINITIONS
directly
or via target_compile_definitions()
:
# 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
COMPILE_DEFINITIONS_<CONFIG>
target property when generating the
compilation command. The NEW behavior for this policy is to ignore the content
of the COMPILE_DEFINITIONS_<CONFIG>
target property .
This policy was introduced in CMake version 3.0. CMake version 3.14.7 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
