This compiles and installs the library and header file to the appropriate directories. By default, /usr/local/lib and /usr/local/include.
You can change the destination directory by passing some options to the configure script. Run "./configure --help" to see the list of options.
It also installs a binary "qrencode" to /usr/local/bin. If you want not to install it, give "--without-tools" option to the configure script.
