how to compile Marble (KDE) on macOS? No pre built package available Marble is an Open Source alternative to Apple Maps / Google Earth:


  Versatile, yet easy to use. Use Marble similar to a desktop globe; pan
  around and measure distances. At closer scale it becomes a world
  atlas, while OpenStreetMap takes you to street level. Search for
  places of interest, view Wikipedia articles, create routes by drag and
  drop and so much more.
