# note 1: remove or set -DCMAKE_SUPPRESS_REGENERATION=OFF to reenable ZERO_CHECK target which checks for CMakeLists.txt changes and re-runs CMake before builds
# however, if ZERO_CHECK is reenabled **must** add VULKAN_SDK location to Xcode Custom Paths (under Prefs/Locations) otherwise build failures may occur
# note 2: env variable MVK_CONFIG_FULL_IMAGE_VIEW_SWIZZLE=1 enables imageViewFormatSwizzle which may be required on older macOS versions or hardware (see vulkaninfo)
