How to build Linuxcnc?

Although the official website of LinuxCNC provides a ready-made ISO file, I do not want to install LinuxCNC through the ISO file. I would like to ask my friends if they have constructed a tutorial. I tried to operate according to the tutorial on the official website of LinuxCNC, but finally FAILED. Can you share your tutorial with me?

Once you get the dependencies sorted, the linucnc instructions are perfect
linuxcnc.org/docs/devel/html/code/building-linuxcnc.html
But starting from scratch on Debian 11 and installing the dependencies takes some effort.
This tutorial is by far the best out there and includes the stuff you need to run qtpyvcp and probably qtvcp
