Bug#814606: libvigraimpex: FTBFS on armel (error: return type 'class std::future<void>')

[Ullrich Koethe]

Since your toolchain apparently has no conforming implementation of 
std::thread, you might want to try boost::thread as a fall-back. To do 
so, please run cmake with the flag "-DWITH_BOOST_THREAD=1".
