When Slang outputs HLSL it typically does not contain any `#include`, because all of the `#include` in the original source code have been handled by Slang. Slang then outputs everything required to compile to the downstream compiler *without* any `#include`. When NVAPI is used explicitly this is still the case - the NVAPI headers are consumed by Slang, and then Slang will output HLSL that does not contain any `#include`. -The astute reader may have noticed that the new default Slang HLSL prelude *does* contain an include.
