The distribution comes with, in addition to the library, several test programs.
While the core library is very portable, these programs have some additional
dependencies. All of them require libjpeg, and two (`quirc-demo` and `inspect`)
require SDL. The camera demos use Linux-specific APIs:
dependencies as documented below.

additional information on stdout.
