Changes required for > v0.14.0?

Start by reproducing the reported command with Zig 0.15.1 and target x86_64-linux-musl using the shown build.zig.zon and build.zig. Then inspect the dependency build.zig locations named in the errors, including the ConfigHeader and zlib integration sites. Done means the dependency builds and the example project completes zig build for that target.

I want to pull in this dependency in my project so my program can ingest python scripts and run them with some behaviour added. But just trying to get a basic version of this dependency pulled in on zig v0.15.1 doesn't work. Here is the basic and relevant examples:

build.zig.zon:

.{
    .minimum_zig_version = "0.15.1",
    .dependencies = .{
        .cpython = .{
            .url = "git+https://github.com/allyourcodebase/cpython.git#b9871b745dd11dd9b08e7ad1c8493403149a6f08",
            .hash = "cpython-0.0.0-FN2rG3bEAQBfgfSVEVG1RkY4uwykTHwl6wM2gOD9xHMD",
        },
    },
}

build.zig:

const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const cpython_dep = b.dependency("cpython", .{
        .target = target,
        .optimize = optimize,
    });
    const cpython_module = cpython_dep.module("cpython");

    const exe = b.addExecutable(.{
        .name = "testing",
        .root_module = b.createModule(.{
            .root_source_file = b.path("src/main.zig"),
            .target = target,
            .optimize = optimize,
        }),
    });

    exe.root_module.addImport("cpython", cpython_module);

    b.installArtifact(exe);
}

the command im running and zig version:

If this is something different and this is actually a me problem i apologise but would very much appreciate you pointing me in the right direction. I have not been able to figure this out and grok is suggesting is incompatibility with my zig version.
