        Compatibility with CMake < 3.10 will be removed from a future version of
        CMake.
      
        Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
        to tell CMake that the project requires at least <min> but has been updated
        to work with policies introduced by <max> or earlier.

        The OLD behavior for policy CMP0148 will be removed from a future version
        of CMake.
      
        The cmake-policies(7) manual explains that the OLD behaviors of all
        policies are deprecated and that a policy should be set to OLD only under
        specific short-term circumstances.  Projects should be ported to the NEW
        behavior and not rely on setting a policy to OLD.
