The variable_requires() command should not be called.
This command was introduced in November 2001 to perform some conditional
logic. It has long been replaced by the if() command.
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.
CMake version 3.23.5 warns when the policy is not set and uses
OLD behavior. Use the cmake_policy() command to set it to OLD or
NEW explicitly.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
