How to use a multiple file library with requireJs

I building a project with requireJs my file structure is the following:

js/
   lib/
       noty/
           layouts/
               bottom.js
               top.js
               ...
           themes/
               default.js
           noty.jquery.js
       jquery.js
       jquery-ui.js
   user/
      user.js
   app.js

And my configuration :

    requirejs.config({
        baseUrl: 'js/lib',
        urlArgs: 'bust=' + (new Date()).getTime(),  //only for dev  : no-cache
        paths: {
            user: '../user'
        },
        shim: {
            'jquery-ui': ['jquery'],
            'jquery-tmpl': ['jquery'],
            'gridy': ['jquery']
        }
    });
    requirejs(['jquery', 'jquery-ui'],  function($){
    ....
    });

My concern is about to integrate noty which is a notification plugin that I may use in any modules. This plugin requires to load :

js/lib/noty/noty.jquery.js
js/lib/noty/layout/top.js
js/lib/noty/themes/bottom.js

I'm not sure what is the way to do that?

Concatenate the files ?
Load each file as a dependency? :

requirejs(['jquery', 'jquery-ui', 'noty/noty.jquery.js', 'noty/layout/top.js', etc. ]
Creates some kind of plugin/module for requireJs?

Thanks

Solution

Finally I managed to implement the 3rd solution: I've created a web module that wrap the library in a file named notiy.js :

define(['jquery',
    'noty/layouts/topCenter', 
    'noty/layouts/bottomRight',
    'noty/themes/default'], 
function($){

$.noty.defaults.timeout = 20000;

return  function(type, msg){
    var topLayout = 'topCenter',
        bottomLayout = 'bottomRight',
        layout = {
            'alert'     : topLayout,
            'info'      : bottomLayout,
            'confirm'   : topLayout,
            'success'   : bottomLayout,
            'error'     : topLayout,
            'warning'   : topLayout
        };

    if(msg && type){
        return noty({
            text : msg, 
            layout: layout[type] || topLayout, 
            type : type
        });
    }
}
});

I've declared the dependencies in the shim config (to fix the dependency order) in my app.js :

requirejs.config({
baseUrl: 'js/lib',
urlArgs: 'bust=' + (new Date()).getTime(),  //only for dev  : no-cache
paths: {
    user: '../user'
},
shim: {
    'jquery-ui'         : ['jquery'],
    'jquery-tmpl'       : ['jquery'],
    'gridy'             : ['jquery'],
    'noty/jquery.noty'  : ['jquery'],
    'notify'            : ['noty/jquery.noty']
}
});
requirejs(['jquery', 'jquery-ui', 'jquery-tmpl', 'notify'],  function($, ui, tmpl, notify){
//...
});

Ans it works like a charm!
