Cake PHP 2 App::build() load CSS from custom module

Question

I'm working on a Cake PHP 2 project that has a custom module system allowing for a folder within app called modules, and then each module can have Views, Controllers, Models etc... I've extended it to include a webroot directory with a css directory inside and have added these directories to my App::build() array.

I've got some css in my module, and a layout which is working, but trying to load my module's css doesn't load it and instead is trying to pull the css from my main app's webroot, where of course it doesn't exist.

What am I missing?

My paths are:

• app/modules/QueueManagerModule/webroot/css/queue.css
• app/modules/QueueManagerModule/View/Layouts/QueueManagerLayout.ctp

I'm doing the following inside of my layout to echo CSS:

echo $this->Html->css('queue');

This though generates the path of: mydomain.com/css/queue.css.

My module set up for loading everything looks like:

<?php
App::uses('BaseModule', 'Modules');
App::uses('CakeEventManager', 'Event');
/**
 * Helper class to  load modules of a specific format from /app/modules directory,
 * and create instances that can connect to system events, modify system behaviours etc.
 *
 * Usage:
 *
 *      $_modules = new Modules();
        $mods_arr = $_modules->initModules(ROOT.'/app/modules');
 *
 *

class Modules
{
    public function initModules($modules_base_dir)
    {
        $modules = array();

        //loop over all directories in /app/modules/
        foreach (new DirectoryIterator($modules_base_dir) as $dir)
        {
            if($dir->isDot()) continue;
            if($dir->getFilename()=='.svn') continue;
            if($dir->isFile()) {
                continue;
            }

            //compile a list of all modules, and load each Module class
            $classname = $dir->getFilename();

            App::import('modules/'.$classname, $classname);
            $module = new $classname();
            array_push($modules, $module);

            //enumerate all events from BaseModule so we know what we need to handle
            $base_events_array = array();
            $methods = get_class_methods('BaseModule');
            foreach($methods as $method)
            {
                //strip out any method that starts with "handle_"
                if(substr($method, 0, 7)=='handle_')
                {
                    $base_events_array[] = substr($method, 7);
                }
            }
