Current state is this:
I have a library `libexample_zig.a` in `/home/protheory8/example_zig/zig-cache/lib` directory.
I'm trying to link it from file `/home/protheory8/test-project/build.zig` using:
```
const exe = b.addExecutable("test-project", "src/main.zig");
exe.addLibPath("/home/protheory8/example_zig/zig-cache/lib");
exe.setTarget(target);
exe.setBuildMode(mode);
exe.linkLibC();
exe.linkSystemLibrary("example_zig");
exe.install();
```
and then in `src/main.zig`:
```
const example_zig = @import("example_zig");
```

Also tried changing `exe.linkSystemLibrary("example_zig");` to `exe.linkSystemLibrary("example_zig.a");`, `exe.linkSystemLibrary("libexample_zig");` and `exe.linkSystemLibrary("libexample_zig.a");`
