Step 1: Subclass Utils::OutputLineParser and override the handleLine() 
function. This gives you the application output, line by line. Pass it 
on to your business logic and return Status::NotHandled.

Step 2: Subclass ProjectExplorer::OutputFormatterFactory. In the 
constructor, do something like this:

     setFormatterCreator([](Target *t) -> QList<OutputLineParser *> {
         return {new MyOutputParser};
     });

Step 3: Instantiate this factory class somewhere "persistent", e.g. as a 
member of your Plugin class.


That should be it.

All of this assumes that you do not have your own RunConfiguration 
subclass, but you really want to capture any run control's output.
