cmMakefile: Impose maximum recursion limit

In order to keep infinitely-recursive scripts from causing a stack
overflow in the CMake executable, CMake now imposes a maximum
recursion limit before issuing an error message. The limit can be
adjusted at runtime with CMAKE_MAXIMUM_RECURSION_DEPTH.

Fixes: #18694
