Building RT Kernel on Debian 12

Building RT Kernel on Debian 12 was created by JT
The packages libqt4-dev and kernel-package is not in Debian 12. I think I found the replacement for libqt4-dev with qtbase5-dev as make xconfig works but I can't find a replacement package for kernel-package.
Edit: I can't find fully preemptable kernel option with the search tool.
Edit: Ctrl F and full finds the fully preemptable kernel.

Doing sudo make modules_install I get the following error:

After running make xconfig and just selecting the rt kernel I get this in the terminal.

I tried again and only selected the rt kernel it seems to be building... the first time I deselected stuff like wifi and bluetooth and industrial and a few other things... maybe that was not a good idea.

This is what I ended up doing for 4.19.265:
JT
cd ~
sudo apt update
sudo apt install build-essential bison flex bin86 qtbase5-dev
sudo apt install libncurses-dev pkg-config libelf-dev libssl-dev
mkdir k4-19-265
cd k4-19-265
wget https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/linux-4.19.265.tar.xz
wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/4.19/patch-4.19.265-rt117.patch.gz

gunzip patch-4.19.265-rt117.patch.gz
cp patch-4.19.265-rt117.patch linux-4.19.265
cd linux-4.19.265
cat patch-4.19.265-rt117.patch | patch -p1
make xconfig
make -j $(nproc)
sudo make modules_install

Hmm maybe you can't build a 4.x kernel on:
I got the same error as before with sudo make modules_install

Maybe you can't build a 4.x kernel from 6.x...
This is how I did 6.0.5
