lgtm just nits

```sh
sudo apt-get install libzstd-dev
```
Note that the libzstd-dev package provided on Ubuntu 24.04 has a bug and the zstd static library is not built with `-fPIC` flag. Linking to this library will result in a build failure. For example: [Issue#15935](https://github.com/intel/llvm/issues/15935). As an alternative, zstd can be built from source either manually or by using the [build_zstd_1_5_6_ub24.sh](https://github.com/intel/llvm/blob/sycl/devops/scripts/build_zstd_1_5_6_ub24.sh) script.

Sure, but let's do that change in a separate PR. I am not sure if the new Windows machine that we recently added (on VM) has zstd installed.
