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.
OLD behavior for this policy is to allow the command to be called.
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.
CMake version 3.24.0-rc2 warns when the policy is not set and uses
OLD behavior. Use the
cmake_policy() command to set it to

deprecated by definition
and may be removed in a future version of CMake.
