Since #15 (Update runtime to 21.08) was merged, support for Vulkan output should be possible.
Unfortunately, it looks like it will take more than a simple manifest file change.
Recompiling it fails to enable vulkan support and it looks like many of the dependencies for vulkan are already in the runtime/sdk but fail to get picked up during compilation. Manually adding them doesn't change much as some dependencies seem to require manual patching to work within the runtime.
