Warning
The OLD behavior of this policy was removed
in CMake version 4.0.
This policy must be set to NEW by a call to
cmake_minimum_required() or cmake_policy().
The subdir_depends() command should not be called.
The implementation of this command has been empty since December 2001 but was kept in CMake for compatibility for a long time.
CMake >= 3.0 prefer that this command never be called.
The OLD behavior for this policy is to allow the command to be called.
The NEW behavior for this policy is to issue a FATAL_ERROR when the
command is called.
This policy was introduced in CMake version 3.0.
Prior to removal in CMake version 4.0, it could be
set by cmake_policy() or cmake_minimum_required().
If it was not set, CMake warned, and used OLD behavior.
