Hello!
First at all, thank you for this utility to apply themes to i3wm!
I'm currently trying to install it in a Debian 12 with script ./install_debian. And some missing requirement needs to be install first in my case. I executed python3 -m pip install -r requirements.txt the first thing.
- cmake (should be specify a version?)
- sphinx (via this link) (should be specify a version?)
- pkgconfig (via
sudo apt-get install pkgconfig) (should be specify a version?)
- cairo-fc (I don't know right know ho to install it)
I am blocked in the following error and I don't know actually how to solve:

Also, I don't have the folder polyboard in i3wm-themer :(
If I discover something more, I will upload this issue.
Anyone have the same issue? Thanks in advance.
