-------
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.
