+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.

 This often happened when you are using 64-bit CentOS 7.x.
 And it's because of the libraries that the qBittorrent need are not in `/usr/lib64/`.
