New in version 3.27.
AUTOMOC include directory is a system include directory by default.
Headers generated for AUTOMOC are placed in target-specific include directories. CMake 3.26 and older added these as normal include directories. CMake 3.27 and newer prefer to add them as system include directories. This policy provides compatibility for projects that have not been updated to expect this.
If the AUTOGEN_USE_SYSTEM_INCLUDE
target property is set,
perhaps via the CMAKE_AUTOGEN_USE_SYSTEM_INCLUDE
variable,
then its value is used regardless of the setting of this policy.
The OLD
behavior for this policy is to add autogen include directory to
the target's include directories.
The NEW
behavior for this policy is to add autogen include directory to
the target's system include directories.
This policy was introduced in CMake version 3.27.
It may be set by cmake_policy()
or cmake_minimum_required()
.
If it is not set, CMake does not warn, and uses OLD
behavior.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
