I am completely new to zig and system programming. I do not understand anything from the zig build system and I want to include glfw and xcb.zig in my project. I have been looking for documentations on zig build system and using git to load packages but i keep getting errors. My zig version is 0.13.0 as I installed it with arch linux package manager. Here is how I proceed.

I start with xcb.zig first. I run zig init in an empty directory named test. Then I add these two lines in my build.zig just after const exe = ... definition:

const xcb = b.dependency("xcb.zig", .{});
exe.root_module.addImport("xcb.zig", xcb.module("xcb.zig"));

Then I use the terminal in project location (test directory) and run `zig fetch --save git+url.

This should import xcb.zig library to my project. To use it I only need to write const xcb=@import("xcb.zig"); in my main.zig, right? I run zig build to test it and get some error (I assume I have to do the same process when dealing with glfw:
