Hm!  pkg-config!  Yes, that's a good idea; we should support that in
libevent 2.0 and later.  Would you like to write a patch to
libevent to add pkg-config support?

You could just search for a header called event.h that defines
event_init, and flags like -levent-core that defines event_init.

If you want to abuse autoconf and look in a bunch of likely places for
the headers and libraries, you could try to see what Tor does, but I'm
afraid it's a little baroque.  Look in
  https://www.torproject.org/svn/trunk/configure.in
for mention of libevent, and in
  https://www.torproject.org/svn/trunk/acinclude.m4
for a definition of the TOR_SEARCH_LIBRARY macro.

(Yes, this is an ugly and underdocumented hack.  Sorry.  All of it
seemed important at the time.)
