configure: error: Package requirements (libtorrent-rasterbar >= 1.2.12) were not met:
Requested 'libtorrent-rasterbar >= 1.2.12' but version of libtorrent-rasterbar is 1.2.6
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables libtorrent_CFLAGS
and libtorrent_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
