| |
| 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. |
