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 :prop_tgt:`AUTOGEN_USE_SYSTEM_INCLUDE` target property is set, +perhaps via the :variable:`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. Use the +:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. +Unlike many policies, CMake version |release| does *not* warn +when this policy is not set and simply uses ``OLD`` behavior. + +.. include:: DEPRECATED.txt |
