trying to get it to compile, using dynamic libjpeg since static no longer easily available, changing jpeg2000 dependency to default off since most people will not need it, using jpgTilesX.h as a minimal include file removes the conflict over "boolean" between common.h and libjpeg.h

/****************************************************
**
** FILE: jpgTiles.h (uses libjpeg)
** CREATED: 6th February 2006
** AUTHOR: Galt Barber
**
** PURPOSE: Convert input RGB data rows to jpg tile-set and thumbnail and optionally
** a full-size jpg for downloading as well.
** Call jpgTiles with image width and height and outdir and outpath
** Quality settings can also be optionally specified.
** [-quality N|-variable 50 60 70 80 85]
** Currently just operates on one output image tileset and stops,
** so run the program again for each input image.
**
** NOTES:
** Keeps the same size image as input and uses RGB 3-band 24-bit color
** with default quality 75%. Caller must create a subdir under outdir with the root name of
** the infile, i.e. infile/ and it puts the tiles for levels 0-4 there,
** each higher level zooms out by 2 in both dimensions.
** N is % quality, from 3 to 95 and is optional, otherwise uses libjpeg default (75%).
