themes.forEach(function (theme) {
    Encore.addStyleEntry('css/themes/' + theme + '/default', './assets/css/themes/' + theme + '/default.css');

    // Copy images from themes into public/build
    Encore.addPlugin(new CopyPlugin({
        patterns: [{
            from: 'assets/css/themes/' + theme + '/images',
            to: 'css/themes/' + theme + '/images'
        }]
