`pip install .` causes messy directory layout

[matthiasdiener]

Describe the bug pip install . seems to write pyopencl files into the main environment:

$ pip install .
[...]
$ pip uninstall pyopencl
Found existing installation: pyopencl 2024.2.2
Uninstalling pyopencl-2024.2.2:
  Would remove:
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/CITATION.cff
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/CMakeLists.txt
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/LICENSE
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/Makefile.in
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/README.rst
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/README_SETUP.txt
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/aksetup_helper.py
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/configure.py
    /Users/mdiener/Work/emirge/miniforge3/envs/ceesd/contrib/cldis.py
[...]

To Reproduce Steps to reproduce the behavior:

1. $ cd pyopencl
2. $ pip install .
3. $ pip uninstall pyopencl

Expected behavior Keep the files in the pkgs/pyopencl-* subdirectory.

Environment (please complete the following information):

• OS: MacOS
  • PyOpenCL version: 2024.2.2

Ugh. I can reproduce this, too. I'm not sure what's causing it.

https://github.com/wjakob/nanobind_example/commit/4df3213af19f658ef5d7efc9839f4f9fe5a30749

is the last commit of nanobind-example before the switch to scikit-build-core. It doesn't seem to have this problem. Neither does islpy.

[inducer]

Migrating to scikit-build-core might also fix this, but I think it'd be kind of a big lift.

Could be related to this: the current wheels on PyPI contain many superfluous files from the source distribution that get installed into the Python root folder (at least on Windows). Quite messy.
