How to compile Leptonica with JPEG support
===

       
I am using leptonica 1.68 to preprocess images for my iOS app..
 When i use the method pixRead(...) pixRead to convert UIImage to PIX it shows the following error


> Error in pixReadStreamJpeg: function not present
Error in pixReadStream: jpeg: no pix returned
Error in pixRead: pix not read
Error in pixGetDimensions: pix not defined
Error in pixGetColormap: pix not defined
Error in pixClone: pixs not defined
Error in pixGetDepth: pix not defined
Error in pixGetWpl: pix not defined
Error in pixGetYRes: pix not defined

 So i need to compile leptonica with JPEG Support... How to do it??
