Minetest build from stable-5 branch requires irrlichtmt version that differs from the stable-5 version of the build documentation

Operating system and version

Summary

I noticed that the documentation for building Minetest mentions to clone from https://github.com/minetest/irrlicht.git that contains IrrlichtMt 1.9.0.15 but the CMakeLists.txt requires IrrlichtMt 1.9.0mt13 to build. How do i resolve this conflict?

Steps to reproduce

1. Follow the documentation except to clone from master-5 instead of the default branch of the repository
2. Attempt to build it

You should switch the irrlicht branch to 1.9.0mt13. The release notes of both 5.8.1 and 5.8.0 say to use 1.9.0mt13

https://github.com/minetest/minetest/releases/tag/5.8.0
https://github.com/minetest/minetest/releases/tag/5.8.1-android

Note that this problem is going away in 5.9.0 as the irrlicht repo is no longer used

@rubenwardy The documentation tells users to get version 1.9.0.15 of irrlichtMt via cloning the Github repository of irrlichtMt. I believe that there should be a note about how to obtain older versions of irrlichtMt

I made a script that builds Minetest from stable-5 automagically

# Installs all dependencies of the build
sudo apt-get install g++ make libc6-dev cmake libpng-dev libjpeg-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev libcurl4-gnutls-dev libfreetype6-dev zlib1g-dev libgmp-dev libjsoncpp-dev libzstd-dev libluajit-5.1-dev gettext libsdl2-dev
# Gets the stable-5 branch of the Minetest project
git clone --depth 1 -b stable-5 https://github.com/minetest/minetest.git
# Installs the correct version of IrrlichtMt for stable-5
cd minetest/lib
wget https://github.com/minetest/irrlicht/archive/refs/tags/1.9.0mt13.zip && unzip 1.9.0mt13.zip && mv irrlicht-1.9.0mt13 irrlichtmt && rm 1.9.0mt13.zip
cd ..
# CMake & Make
cmake . -DRUN_IN_PLACE=FALSE -DCMAKE_BUILD_TYPE=Release

This script first installs all the dependencies, then downloads Minetest from stable-5 branch, downloads the correct IrrlichtMt, builds Minetest and cleans up all files that are no longer needed from the game, leaving behind a portable Minetest build for the architecture of the computer the script was made for
