      *** CMake build failed
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pyopencl
Failed to build pyopencl
ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (pyopencl)

To Reproduce
Steps to reproduce the behavior:

1. Install python3.13 (i always installed 3.13t too)
2. select 3.13 or 3.13t as your interpreter
3. install pyopencl using py -m pip install pyopencl
4. See error above shown

Environment (please complete the following information):

• OS: Windows 10/11
• ICD Loader and version: [e.g. ocl-icd 2.3.1]
• ICD and version: [e.g. pocl 1.8]
• CPU/GPU: Ryzen 7 3800x with 2060OC / Intel i7 7th gen with 940mx / intel 640
• Python version: 3.13 / 3.13t
• PyOpenCL version: latest (2024.3)

Is pyopencl even supported on 3.13? I couldn't find any concrete information on that, neither in forums, pypi nor here on github.

From your install log:

Cannot open include file: 'CL/cl.h'

You're missing OpenCL headers. If you have them installed somewhere that CMake's OpenCL finder doesn't look by default, you can specify the spot manually.

3.13 is supported, has been for a while.
