Instead of using the full fledged Vulkan SDK, we only can use the Vulkan-headers package and load actual Vulkan implementation from the driver.
To do this, we need to enable vulkan.hpp dynamic dispatcher by default by setting VULKAN_HPP_DISPATCH_LOADER_DYNAMIC to 1, adding VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE to the source file and updating VULKAN_HPP_DEFAULT_DISPATCHER as we load in more Vulkan features.
#define VULKAN_HPP_DISPATCH_LOADER_DYNAMIC 1
#include "vulkan/vulkan.hpp"
// Vulkan defined macro storage for dispatch loader
VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE
int main()
{
vk::DynamicLoader dl;
PFN_vkGetInstanceProcAddr vkGetInstanceProcAddr = dl.getProcAddress<PFN_vkGetInstanceProcAddr>("vkGetInstanceProcAddr");
VULKAN_HPP_DEFAULT_DISPATCHER.init(vkGetInstanceProcAddr);
vk::Instance instance = vk::createInstance({}, nullptr);
// initialize function pointers for instance
VULKAN_HPP_DEFAULT_DISPATCHER.init(instance);
// create a dispatcher, based on additional vkDevice/vkGetDeviceProcAddr
std::vector<vk::PhysicalDevice> physicalDevices = instance.enumeratePhysicalDevices();
vk::Device device = physicalDevices[0].createDevice({}, nullptr);
// function pointer specialization for device
VULKAN_HPP_DEFAULT_DISPATCHER.init(device);
}
