[ESP32-C3] How do I correctly setup the blink example on my own repository

[JanBeelte]

Hello together,

I am pretty new to the zig build system and struggeling to setup ESP32-C3 support on my own repository using microzig as a dependency. Currently I have the following in my build.zig.zon file:

.{
    .name = "firmware/blink",
    .version = "0.0.0",
    .dependencies = .{
        .@"microzig/build" = .{  
            .url = "git+https://github.com/ZigEmbeddedGroup/microzig.git#d6a97c9476c3377877946873cad040f769e42698",
            .hash = "12204ade9b0ef08b6787667a99396aa1e89e8a6dca1e25b62b9490e3ab8394a0383c" },
        .@"microzig/port/espressif/esp" = .{ 
            .url = "git+https://github.com/ZigEmbeddedGroup/microzig.git#d6a97c9476c3377877946873cad040f769e42698",
            .hash = "12204ade9b0ef08b6787667a99396aa1e89e8a6dca1e25b62b9490e3ab8394a0383c" },
    },

    .paths = .{
        "LICENSE",
        "README.md",
        "build.zig",
        "build.zig.zon",
        "src",
    },
}

This can obviously not work as I am using the same url for both dependencies. How do I do this correctly?
Also I am a bit confused by the error message from zig build:

❯ zig build

Is this error even linked or completely unrelated?

Thanks for your help!

Best,

I'm new to this zig & this community but I was able to get the RP Pico to blinky in a separate repo.
Not sure it's helpful to you or others but I'll share it here just in case.
