# CMP0133

New in version 3.24.

The `CPack` module disables SLA by default in the `CPack DragNDrop Generator`.

The `CPack DragNDrop Generator` in CMake 3.22 and below attach a Software License Agreement (SLA) to `.dmg` files using the file specified by `CPACK_RESOURCE_FILE_LICENSE`, if set to a non-default value. macOS 12.0 deprecated the tools used to do this, so CMake 3.23 added the `CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` option to control the behavior. CMake 3.23 enables that option by default for compatibility with older versions. CMake 3.24 and above prefer to not enable the `CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` option by default. This policy provides compatibility with projects that have not been updated to account for the lack of a SLA in their `.dmg` packages.

The `OLD` behavior for this policy is to enable `CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` by default. The `NEW` behavior for this policy is to not enable it by default.

This policy was introduced in CMake version 3.24. Use the `cmake_policy()` command to set this policy to `OLD` or `NEW` explicitly. Unlike many policies, CMake version 3.26.0-rc5 does not warn by default when this policy is not set and simply uses `OLD` behavior. See documentation of the `CMAKE_POLICY_WARNING_CMP0133` variable to control the warning.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
