NOTE: The demo application requires the user space driver libcifx to be compiled with the enabled Toolkit
      Hardware Interface (automake: --enable-hwif).
      The example is based on the Linux spidev interface.
      Building the application for another target can be done by setting the environment variable CC to the
      specific compiler.
      
      For detailed information refer to chapter the Linux cifX Driver documnetation, chapter 4.3 Support
      for non-PCI devices.
