How can I use Metal on Mac and where can I download DiligentCorePro module?

[zhuyaoyuTS]

➜ DiligentEngine git:(master) cmake -S . -B ./build/MacOS -G "Xcode"
Target processor: arm
CMake generator: Xcode
Target platform: MacOS 64
DiligentCorePro module is not found. Metal backend will be disabled

D3D11_SUPPORTED: FALSE
D3D12_SUPPORTED: FALSE
GL_SUPPORTED: TRUE
GLES_SUPPORTED: FALSE
VULKAN_SUPPORTED: TRUE
METAL_SUPPORTED: FALSE
WEBGPU_SUPPORTED: FALSE

-- optimizer enabled
-- SPIRV-Cross: Finding Git version for SPIRV-Cross.
-- SPIRV-Cross: Git hash: diligent-v2.5.6-141-gfa342159
-- Architecture: arm64

The above is my compilation information, based on the master branch version on May 8.
It seems that the problem is "DiligentCorePro module is not found. Metal backend will be disabled"

How should I solve it? I can't find any relevant tutorials, thank you very much! !
