Managed to get it compiling using  https://vulkan.lunarg.com/sdk/home

I did:

wget -qO - https://packages.lunarg.com/lunarg-signing-key-pub.asc |
sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-1.2.176-focal.list
https://packages.lunarg.com/vulkan/1.2.176/lunarg-vulkan-1.2.176-focal.list
sudo apt update
sudo apt install vulkan-sdk

It doesn't work, however, It segfaults:
