Didn't say I didn't understand it, I just said it was less explicit. Read through the Zig and it is super clear what every step is doing, and it sets things much more explicitly than the meson build

``` const wayland_version_header = b.addConfigHeader(.{ .style = .{ .cmake = upstream.path("src/wayland-version.h.in") }, }, .{ .WAYLAND_VERSION_MAJOR = @as(i64, @intCast(version.major)), .WAYLAND_VERSION_MINOR = @as(i64, @intCast(version.minor)), .WAYLAND_VERSION_MICRO = @as(i64, @intCast(version.patch)), .WAYLAND_VERSION = b.fmt("{f}", .{version}), });

```

which is doing some config automake work. Which Meson does implicitly(magically).
