1CMP0106 2------- 3 4.. versionadded:: 3.18 5 6The :module:`Documentation` module is removed. 7 8The :module:`Documentation` was added as a support mechanism for the VTK 9project and was tuned for that project. Instead of CMake providing this module 10with (now old) VTK patterns for cache variables and required packages, the 11module is now deprecated by CMake itself. 12 13The ``OLD`` behavior of this policy is for :module:`Documentation` to add 14cache variables and find VTK documentation dependent packages. The ``NEW`` 15behavior is to act as an empty module. 16 17This policy was introduced in CMake version 3.18. CMake version |release| 18warns when the policy is not set and uses ``OLD`` behavior. Use the 19:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. 20 21.. include:: DEPRECATED.txt 22
