      # The default Travis Linux image is Ubuntu 12.04 precise, which is way too old:
      # - cmake version is 2.8.7
      # - wget doesn't support SNI, so dowloading with HTTPS from cmake.org fails. The correct 
      #   solution is NOT --no-check-certificate as wget suggests! The correct solution is to
      #   use a more recent wget or something that supports SNI.
      #
      # Switch from Ubuntu 12.04 precise to 14.04 trusty (which is still old but the most
      # recent version available on travis, in beta since November 2016).
      # By default:
      # - cmake version is 3.2.2
      # - gcc version is 4.8.4
      # - qt5 version is 5.2.1, while we require at least 5.6
      #
      # See http://stackoverflow.com/a/29818514/561422 for the proper way to get any Qt5 version
      # with Travis and 14.04 trusty!
