.. versionadded:: 3.18

Multiple calls to :command:`export` command with same ``FILE`` without
|
||
|
|
``APPEND`` is no longer allowed.
|
||
|
|
|
||
|
|
In CMake 3.17 and below, multiple calls to :command:`export` command with the
|
||
|
|
same ``FILE`` without ``APPEND`` are accepted silently but only the last
|
||
|
|
occurrence is taken into account during the generation.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to ignore the multiple occurrences of
|
||
|
|
:command:`export` command except the last one.
|
||
|
|
|
||
|
|
The ``NEW`` behavior of this policy is to raise an error on second call to
|
||
|
|
:command:`export` command with same ``FILE`` without ``APPEND``.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.18. CMake version
|
||
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior.
|
||
|
|
Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW``
|
||
|
|
explicitly.
