1. Why you are building debug tesseract? 2. Why you are mixing build tools (cmake for leptonica and autotool for rest)? There was reported issue regarding this mix in case of leptonica->tesseract... 3. jped. png, tiff are common lib heavily used by desktop system. Replacing system-wide libs with custom build is very bad idea, because you can break think you have no clue. Using system provided libs is much better solution.
