Unable to install on CachyOS (Arch-based)

I'm getting this error:

The headers are installed:

How do I solve this issue?

Hey, I'm new to kernel modules, but if I'm not mistaken /usr/lib/modules/6.11.0-5-cachyos-lto/build is a part of the kernel headers..
Could you ensure that the appropriate headers are installed? It should be something in the style of cachyos-lto-headers in your package manager.

Hey, thanks for the reply. The cachyos-headers package is installed.

How did you install?
Did you clone the repo and run sudo ./install.sh or did you curl -fsSL https://www.maccel.org/install.sh | sudo sh?
If you cloned the repo, what is the output of ls -la driver/. aka are all the files there, including the Makefile?
What kernel version are you using uname -r?
And lastly does /lib/modules/`uname -r`/build/Makefile exist?

This fix worked on cachyos.
