Using global variables within module revealing pattern

Let's say that a global variable called "thirdParty" is loaded via a async JS file. As part of module revealing pattern (example below), how can I alter the code to make sure these IIFEs wait for "thirdParty" global variable to be available?

var app = app || {};
app.something = (function(){    
    function run() {
        if(typeof thirdParty !== "undefined") {
        // code within this function doesn't get executed as thirdParty is of type undefined at the time of this function execution
        }
    }
    return {run:run};

})();

// function calls
jQuery(document).ready(function() {
    app.something.run();
});
