@DesPetrie and @WesHildebrandt: I was able finally to build QuaZIP successfully. Unfortunately, I had to resort to using hard-coded Qt paths. Could you please tell me how you would like to handle Qt? It appears that, for the licensed version, we must run the installer. But using an installer would be unlike what we do for the other third-party libraries. Would it be acceptable to treat Qt differently? Or would you like to write a build script for open-source Qt, like we do with the other libraries? Thank you.
