| ExternalProject-no-extract-timestamp | |
| ------------------------------------ | |
| * The :command:`ExternalProject_Add` command gained a new | |
| ``DOWNLOAD_EXTRACT_TIMESTAMP`` option for controlling whether the timestamps | |
| of extracted contents are set to match those in the archive when the ``URL`` | |
| download method is used. A new policy :policy:`CMP0135` was added to control | |
| the default behavior when the new option is not used. |
