:variable:`CMAKE_PARENT_LIST_FILE` is not defined in ``CMakeLists.txt``.
|
|
|
|
CMake 4.1 and below defined ``CMAKE_PARENT_LIST_FILE`` when processing
|
|
a ``CMakeLists.txt`` even though there is no parent file. CMake 4.2
|
|
and above prefer to not define ``CMAKE_PARENT_LIST_FILE``. This policy
|
|
provides compatibility for projects that accidentally relied on the
|
|
old behavior.
|
|
|
|
The ``OLD`` behavior for this policy is to set
|
|
:variable:`CMAKE_PARENT_LIST_FILE` to :variable:`CMAKE_CURRENT_LIST_FILE`
|
|
when processing a ``CMakeLists.txt``. The ``NEW`` behavior for this policy
|
|
is to not set :variable:`CMAKE_PARENT_LIST_FILE`.
