command line with
-DCMAKE_MAXIMUM_RECURSION_DEPTH=<x>, or within
CMakeLists.txt by projects that require a large recursion depth. Projects
that set this variable should provide the user with a way to override it. For

If it is not set, or is set to a non-integer value, a sensible default limit is used. If the recursion limit is reached, the script terminates immediately with a fatal error.
Calling any of the following commands increases the recursion depth:
