How do I add this C library to my iOS Xcode 4 project?
===

I'm trying to add the openjpeg library to my XCode 4 project so that I can compress images taken by the iPhone's camera to jpeg2000.

I built the static library (libopenjpeg.a) using Cmake on OS/X. (I'm guessing this may have been the first error, that it needs to be built by XCode so it's built for iPhone architecture and not OS X).

I have the library added in the **Link Binary with Libraries** of my target.

The project builds successfully but I can't seem to import any of the headers from the library into any of my Objective-C classes. I've tried manually adding the folder that contains the libopenjpeg header files to the User Header Search Path but that did not seem to do anything.

Any suggestions?
