#   --apple-dev-team TEAM_ID  - Apple development team id used for code signing (required for iOS platforms)
#   --apple-deploy-target X.Y - minimum version of Apple OS deployment target (15.0 by default)
#   --debug                   - Debug build instead of Release build by default
#   --vulkan VULKAN_SDK       - use Vulkan graphics API via Vulkan SDK path (~/VulkanSDK/1.2.182.0/macOS) instead of Metal on MacOS by default
#   --graphviz                - enable GraphViz cmake module diagrams generation in Dot and Png formats
#   --analyze SONAR_TOKEN     - run local build with Sonar Scanner static analysis and submit results to the server using token login
