## Build from source:
Ensure you have the following prerequisite packages installed:

- `mkl-devel-dpcpp`
- `dpcpp_linux-64` or `dpcpp_win-64` (depending on your OS)
- `tbb-devel`
- `dpctl`

In addition, you need oneDPL installed on your system. There are two ways to do
so:

1. Install oneAPI and run the oneDPL activation script. E.g., on linux:

```bash
source /opt/intel/oneapi/dpl/latest/env/vars.sh
```

2. Clone dpl from https://github.com/oneapi-src/oneDPL and set the `DPL_ROOT`
environment variable to point to the `include` directory in the repository.

E.g., on linux

```bash
git clone https://github.com/oneapi-src/oneDPL
export DPL_ROOT=$(pwd)/oneDPL/include
```

After these steps, `dpnp` can be built in debug mode as follows:


```bash
git clone https://github.com/IntelPython/dpnp
cd dpnp
