Build errors, can't seem to locate audio libraries

[elliotblackburn]

I'm looking to run a new build of the library so that we can include it into an AIR-21 project as the current one is giving errors when we attempt to package as an IPA. When attempting to build from the xcode project, I'm getting the 6 following errors that seem to suggest it can't locate some libraries. However I can see files that I'd assume are related to most of these such as the lmp3lame. While they're not named the same, I'm assuming these are what it's after.

error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lopencore-amrnb
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lopencore-amrnb is not an object file (not allowed in a library)
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lopencore-amrwb
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lopencore-amrwb is not an object file (not allowed in a library)
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lmp3lame
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lmp3lame is not an object file (not allowed in a library)

I'm aware this project is old and hasn't been updated for quite a while, but we're looking to use the library for a prototype of an app. Sadly the AIR microphone setup isn't giving us the quality we need for it.

Any suggestions or fixes would be really appreciated as I'm at a dead-end and really not sure where to go right now.
