+Tricky -- need to set up without X or Wayland, exact process depends on your GPU hardware.

+Usually, you need to change the ''-Dvulkan-drivers'' and ''-Dgallium-drivers'' options depending on your GPU.
+Intel i915 (Charles): ''meson -Dllvm=disabled -Dglx=disabled -Dplatforms= -Dvulkan-drivers=intel -Dgallium-drivers=i915 -Dbuildtype=release ..''
+You might need to chmod a different ''/dev/dri'' path if no Vulkan device found.
