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().
Error on non-existent dependency in add_dependencies.
CMake 2.8.12 and lower silently ignored non-existent dependencies
listed in the add_dependencies() command.
The OLD behavior for this policy is to silently ignore non-existent
dependencies. The NEW behavior for this policy is to report an error
if non-existent dependencies are listed in the add_dependencies()
command.
This policy was introduced in CMake version 3.0.
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.
