  None of those packages include jpeglib.h.  To find out what cygwin package
contains any particular file, go to http://cygwin.com/packages/ and enter it
into the search box - you'll get to 
http://cygwin.com/cgi-bin2/package-grep.cgi?grep=jpeglib.h
which shows you that the package you want is called jpeg and it's currently at
version jpeg6b-11.  The libjpeg62 that you installed only contains the runtime
dll; what you need is the development package with the link libraries and
headers.

  This isn't what's happened, but if setup had forgotten something, the
correct thing to do would be to re-run it and re-select the package for
install from local directory.
