  1. I’m sure most build systems don’t run on Tianhe-2, so we don’t need one thread per icon.
  2. If someone uses make instead of ninja, make will take very much time to fire up the 2000 (11000 if we also auto-generate dark versions) threads.
  
  I think it makes more sense to define one target for every directory, and then 4 (43) parralel-running Python scripts iterate through their own directory. Then we also don’t need a for loop in cmake.
  
  By the way that inefficient shell script needs only 18 seconds on my slowbook. I think that is fast enough and competitively green enough, and a streamlined Python script will probably be even better.
