With pkg-config we can get a list of Boost components from Libtorrent
dependencies and make qBittorrent depend only on these libraries in
turn. For Windows user may provide a custom list via
LibtorrentRasterbar_CUSTOM_BOOST_DEPENDENCIES variable or use generic
list which consists of date_time, system, chrono, random, thread. As a
note: in case of using fully C++11 build, the actual list contains only
boost system library.
