# Dependency providers were introduced in CMake 3.24. We don't set cmake_minimum_required here because that would
# propagate to downstream projects, which may break projects that rely on deprecated CMake behavior. Since the build
# is using brewed CMake, we can assume that the CMake version in use is at least 3.24.
