CMake 3.15 and below dropped leading zeros from each +component. CMake 3.16 and higher prefer to preserve leading zeros. This +policy provides compatibility for projects that have not been updated to +expect the new behavior. + +The ``OLD`` behavior of this policy drops leading zeros in all components, +e.g. such that version ``1.07.06`` becomes ``1.7.6``. The ``NEW`` behavior +of this policy preserves the leading zeros in all components, such that +version ``1.07.06`` remains unchanged. + +This policy was introduced in CMake version 3.16. Unlike many policies, CMake +version |release| does *not* warn when this policy is not set and simply uses +the ``OLD`` behavior. Use the :command:`cmake_policy` command to set it to +``OLD`` or ``NEW`` explicitly. + +.. include:: DEPRECATED.txt |
