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 It has long been replaced by the if() command.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 3.25.0-rc2 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.
