Thank you for the help, @szabolcsdombi!
And sorry for dealing with this so late.

I realize that this was a bad approach. Obviously I shouldn't copy files around when using setup.py.
The reason why I did it this way is to be able to include the typing data with PyGLM, which, according to my research has to be in a specific directory "<module-name>-stubs" (in this case "glm-stubs") alongside the actual module. This seemed impossible to achive without using pyglm-typing as a submodule and moving the respective files to glm-stubs.

Unfortunately I don't know much about Python typing stubs, especially not for C-API modules. I guess I'll have to research before being able to correctly include the typing stubs. Either way, this PR is currently incomplete, since it removes the copy operations, but still expects typing stubs to exist in "glm-stubs". I'll have to remove typing stubs for the time being and address it at a later time.

-- EDIT
I guess I don't have to use a submodule, I already have a copy of "glm-stubs" in the project anyway, so indeed it does not make sense to have those copy operations. I'll merge the PR as is and try to fix some of the other issues so PyGLM is finally compatible with 3.12

You are experiencing issues with stubs due to they are a fairly new feature.
For example the stubs module seems not to work when you pip install -e . but do from pypi.
Adding a .pyi file in the root works with pip install -e . but not when installed from pypi.
There is a simple reason for this, it is complicated to explain though.

I tried all variations of stubs and I like the stubs module the most for objective reasons.
I even make them optional to include during an install.

I ship no stubs for the web/pyodide version.

If you are into code formatters, black can actually format the pyi files too. you just have to run it on the stubs module.

There is also progress on including pyi files automatically: see: pypa/setuptools#3136 (comment)

I am going to test the master branch with this PR merged, and also with Pyodide.
I already used PyGLM on the web (here), but I was not able to propose a meta.yml for Pyodide due to this bug.
I am very grateful you have merged this, Thank You!

Thanks for letting me know. I thought I was just missing the point or using a deprecated way of providing typing stubs (as I remember having difficulties getting information on how to use the "-stubs" module).

That is most impressive! I didn't know using Python in the web using webassembly was already possible, let alone using OpenGL. Your work is really amazing (not just the PyWeek entry) and I'm honored that you use my humble library.

I am very grateful you have merged this, Thank You!

You're very welcome. Your help and input is always appreciated 😊
