iOS module linker error

Hi,

Okay, another linker error in my module.

I'm pulling code into my module that uses (among many other frameworks) CoreMotion. I have added the Framework in xcode (through Link Binary with Libraries) and I have added CoreMotion to the module.xconfig, but I still get this error while I compile my project that using the module:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_CMMotionManager", referenced from:
      objc-class-ref in libmobi.noster.ar.a(NosterARView.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've seen this almost identical bug, but the resolution is the module.xcconfig thing that I'm already doing. similar question

Any thoughts very welcome! Thanks Bill
