How do I get the path of a script(python) from my qt project, so I can run it during execution?

Basically:

• 
  

  I have a python script I want to execute.

  
  


• 
  

  When I run my program, my build directory does not include the python script.

  
  


• 
  

  Therefore I can not find the file with QDir, unless I manually set it.

  
  

Am I supposed to get it so the .py file is included in my build directory? Or am I missing something here?
