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().
Added in version 3.3.
Do not treat DEFINITIONS as a built-in directory property.
CMake 3.3 and above no longer make a list of definitions available through
the DEFINITIONS directory property. The
COMPILE_DEFINITIONS directory property may be used instead.
The OLD behavior for this policy is to provide the list of flags given
so far to the add_definitions() command. The NEW behavior is
to behave as a normal user-defined directory property.
This policy was introduced in CMake version 3.3.
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.
