Hi. I see this:

  $ pkg-config --cflags aravis-0.8

  Package libusb-1.0 was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libusb-1.0.pc'
  to the PKG_CONFIG_PATH environment variable
  Package 'libusb-1.0', required by 'aravis-0.8', not found

To fix, I need libaravis-dev Depends: libusb-1.0-0-dev.

The .pc file looks like this, so maybe there are other dependencies that
are also missing:

  $ cat /usr/lib/x86_64-linux-gnu/pkgconfig/aravis-0.8.pc

  ....
  Requires: glib-2.0 >= 2.52, gobject-2.0, gio-2.0
  Requires.private: libxml-2.0, zlib, libusb-1.0

Thanks
