Description:             Fixes building tidy-html5 5.8.0 with CMake 4.0. CMake
                         4.0 removes a lot of deprecated syntax from previous
                         versions, and is no longer compatible with files
                         designed to work with versions lower than 3.5. To fix
                         this, I updated the minimum required to include any
                         version up to 4.0 (similar to what other projects
                         have done), and then adjusted the custom commands for
                         manual pages to use the correct syntax.
