Basically, After adding any files, We just need to make some entries<br>
in these two files: <a href="http://configure.ac" rel="noreferrer noreferrer" target="_blank">configure.ac</a> and Makefile.am files.<br>
autoheader, autoconf and automake are the tools used when you execute<br>
autoreconf command. It generate <a href="http://config.h.in" rel="noreferrer noreferrer" target="_blank">config.h.in</a>, Makefile. in and that<br>
configure script and When you execute configure script, you get<br>
config.h and Makefile.<br>
