What are the correct XCode 4.5.2 settings for the compiled framework?

I am trying to build a Titanium iOS module that uses the current 2.4.3 opencv2.framework. The module builds, but when I try to link with another XCode project, I get the listed errors. I have spent quite a bit of time now trying different compiler and dependency settings but can't get it to build without lots of std:: related errors.

Will the App have to built with the same settings as the module? What are the correct settings to work with that framework? Is there a known problem with cvVideoCamera in the latest framework?

Update: I have a project running at the moment with Apple LLVM 4.1 / C++ Language Dialect = compiler default / C++ Standard Library = libc++ (LLVM std lib with C++11 supp). Sources that use OpenCV need to have suffic .mm so they are compiled as Objective-C++ and references to opencv classes need to be namespaced by either using cv::[class] or declaring "using namespace cv;"
