You may well find that libjpeg is already installed on your Cygwin
installation. Otherwise, well, it's easy enough to Google for. You may
find http://apodeline.free.fr/DOC/libjpeg/libjpeg.html to be useful, too.

Please bear in mind that questions about third-party libraries are
generally considered off-topic here; if you need further help, I suggest
asking in a group such as comp.os.linux.development.apps - where, at the
very least, they ought to be able to point you to the most appropriate
newsgroup.

There's one in Basic Algorithms.
At the moment I haven't made it freely available, however.
