Thanks for merging the new upstream release 2.0 of vkd3d. Unfortunately, 
the new release is failing to build on armhf:

Possibly something is going wrong with the use of "DEMO_EMBED" to embed 
the triangle.hlsl source code into the demo executable, which seems to 
be emulating C23 #embed in a mostly-backward-compatible way?

(I can confirm that this demo does work on amd64 and i386, but not 
necessarily on other architectures.)
