The following errors occur when trying to set clang-cl.exe instead of cl.exe as host compiler: ``` [1/39] Building CXX object source\CMakeFiles\ze_loader.dir\lib\ze_libapi.cpp.obj FAILED: source/CMakeFiles/ze_loader.dir/lib/ze_libapi.cpp.obj C:\PROGRA~1\LLVM\bin\clang-cl.exe /nologo -TP -DL0_LOADER_VERSION=\"1\" -DL0_VALIDATION_LAYER_SUPPORTED_VERSION=\"1\" -Dze_loader_EXPORTS -ID:\a\llvm\llvm\build\tools\sycl\plugins\level_zero\level_zero\level_zero_loader\include...

Sub devices and Sysman API

4

Maybe just a clarification is needed. But I see this in the specification: https://spec.oneapi.io/level-zero/latest/core/PROG.html#sub-device-support > ** a sub-device can be partitioned into more sub-devices; e.g. down to a single slice.**...

Explicitly tell users how to include ze_api.h and friends.

5

The CMakeLists.txt file suggests that the main headers are installed to `/include/level_zero/` which would imply that users should `#include ` instead of `#include `. However, the documentation (https://spec.oneapi.com/level-zero/latest/core/INTRO.html#application-binary-interface) states that...
