Add dependencies to build.zig

const imguinz = b.dependency("imguinz", .{});
const dependencies = .{
    "appimgui",      // Simple app framework
    "imspinner",     // ImSpinner
    "imknobs",       // ImKnobs
    "imtoggle",      // ImToggle
 // "another_lib",
};
inline for (dependencies) |dep_name| {
    const dep = imguinz.builder.dependency(dep_name, .{
        .target = target, 
        .optimize = optimize, 
    });
    exe.root_module.addImport(dep_name, dep.module(dep_name));
}
exe.subsystem = .Windows; // Hide console window
