iOS PostProcessBuild using python

I'm using the mod_pbxproj.py script for executing post process commands when building for iOS. I use it to add external dependencies and frameworks from the folder that's usually on my desktop. How can I do that using the cloud build? My project won't compile in xCode without having this external files included.

This is my OnPostProcessBuild editor script:

Code (CSharp):

1. string sdkPath = "/Users/admin/Desktop/SDK/";
2.  
3.         Process pythonProcess = new Process();
4.         pythonProcess.StartInfo.FileName = "python";
5.         pythonProcess.StartInfo.Arguments = string.Format("Assets/Editor/post_process.py \"{0}\" \"{1}\"", pathToBuildProject, sdkPath);
6.  
7.         UnityEngine.Debug.Log(pythonProcess.StartInfo.Arguments);
8.  
9.         pythonProcess.StartInfo.UseShellExecute = false;
10.         pythonProcess.StartInfo.RedirectStandardOutput = false;
11.         pythonProcess.Start();
12.         pythonProcess.WaitForExit();
