As I mentioned in a previous email: you need to build a static leptonica
library with all its dependencies (image libraries) as static libraries.
Maybe it would require more tweaking ;-) :

I would suggest building a minimal leptonica and tesseract library, to
avoid extra work with linking. E.g. if you will open image with other
library (python PIL [1] , opencv [2] ...) you do not any image support in
leptonica - just pass image data to leptonica/tesseract)
