hello-window Example of application with multiple windows, notifications and the main application menu.
hello-vulkan Example of Vulkan initialization. It requires an additional configuration (see below).

To launch the hello-vulkan example it's required to specify environment variables that point to installed Vulkan libraries. To do this, create .env file in project's root directory:

# Replace <...> by actual paths
cat <<EOT >> .env
VULKAN_SDK=<VULKAN_SDK_DIR>/<TARGET_PLATFORM_DIR>
PATH=<VULKAN_SDK_DIR>/<TARGET_PLATFORM_DIR>/bin:$PATH
DYLD_LIBRARY_PATH=<VULKAN_SDK_DIR>/<TARGET_PLATFORM_DIR>/lib:$DYLD_LIBRARY_PATH
VK_ICD_FILENAMES=<VULKAN_SDK_DIR>/<TARGET_PLATFORM_DIR>/share/vulkan/icd.d/MoltenVK_icd.json
VK_LAYER_PATH=<VULKAN_SDK_DIR>/<TARGET_PLATFORM_DIR>/share/vulkan/explicit_layer.d
