ZDOOM on GS for Brutal Doom and other mods!

thanks for the tuto

( instead of download zip from git repo you could directly clone it
also with not directly use gzdoom source ?
git clone https://github.com/coelckers/gzdoom.git --depth 1 && cd gzdoom
in general with cmake we mkdir a build folder before
mkdir build && cd build && cmake .. && make -j4
)

there is a repo, it need packages :- )

ok after some compile time & packaging seem latest release only support opengl >= 3.3

release note of 3.7.2 version seem the last containing “vintage” support for gl2
