tesseract-ocr: new package
Signed-off-by: Gilles Talis <gilles.talis@gmail.com> [Thomas: - remove jpeg, tiff and libpng dependencies, they do not seem to be used - add host-pkgconf as a dependency, since the configure script uses PKG_CHECK_MODULES() - pass --disable-opencl to explicitly disable OpenCL support - add comment to explain why we don't add support for cairo, pango and icu as optional dependencies.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
