CMake 4.0 is more strict than previous versions, and has enforced removals of deprecated syntax. Compatibility with versions of CMake prior to 3.5 is no longer permitted either, so we'll change it to say 4.0 to fix that problem. After that, the custom commands for generating the manual page need to be adjusted as CMake now needs to know when to run commands, so we will generate the manual page after the package is built by passing POST_BUILD to the custom commands. Tested with CMake 4.0 and 3.31.6.

Why don't you simply raise the minimum to something >=3.5, or >=3.10 (to get rid of yet another deprecation warning)? |
