No there is no such thing, however you can create a cmake script file
and then use something like
"cmake -DFOO=123 -P yourscript.cmake"
 to launch a "second" CMake interpreter that will do this evaluation.

This is kind of heavy weight but should work.

You may use
execute_process to launch it at CMake-time
add_custom_command to launch it at Build time.

I'm not sure such footer is appropriate on a pubic, archived and
international mailing list...
