CMAKE_MAXIMUM_RECURSION_DEPTH

Maximum recursion depth for CMake scripts. It is intended to be set on the 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 example:

# About to perform deeply recursive actions
if(NOT CMAKE_MAXIMUM_RECURSION_DEPTH)
  set(CMAKE_MAXIMUM_RECURSION_DEPTH 2000)
endif()

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:
