New in version 3.11.
Default permissions for implicitly created directories during packaging.
This variable serves the same purpose during packaging as the CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS variable serves during installation (e.g. make install).
If include(CPack) is used then by default this variable is set to the content of CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS.
