Instead of "sudo apt-get install libtorrent-rasterbar-dev" install newer versions of libtorrent. (1.1.1+)

libtorrent-1.1.13*
libtorrent 1.2.1

I am able to compile without errors with the latest version. But getting an error with qBittorent linking.

After building and installing libtorrent-rasterbar onto your system do not forget to "ldconfig".

Also as you know qBittorrent supports cmake. It will be easier to building with cmake.

Else you need to pass ./configure --with-something -without-something --enable-something --disable-something and CFLAGS="incl. directory" LDFLAGS="libs directory"
After that if you want a static build LDFLAGS still needed with make command.
