[Windows] level_zero/ze_api.h not found when running UT.

[Stonepia]

Describe the bug

When running the UT on Windows, I got the following error. The Triton needs the level_zero to build, but it can't find it.

Note that in Linux, the level_zero headers come with the driver, but on Windows, we don't have this default behavior. May I ask what should I do?

Correct, download the latest release for Windows from https://github.com/oneapi-src/level-zero/releases and extract it, for example, to c:\level_zero. Then set environment variable ZE_PATH=c:\level_zero.

Thanks for the reply!
Manually downloading the level-zero works great.
May I ask if this is a temporary solution or the next release, we will have level-zero shipped with the driver (which is the same as the behavior of Linux)?
