3030- Type: `[]string`
3131This is a list of relative paths to C source files to compile along with this project. This will be required if you use Zig's [`@cImport`](https://ziglang.org/documentation/master/#cImport), `extern`, etc.

33### `files`
34- Type: `[]string`
35This accepts a list of local directories to embed static assets. These files will be provided through a `self/files` package to `@import(main)`.

37### `root_files`
38- Type: `[]string`
39This accepts a list of local directories to embed static assets. These files will be provided through a `self/files` package to `@import("root")`.
