CMP0133

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 3.25.1 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.
