[ITK-users] Problems with writing filter using Xcode

Hey Matt, 
Here is the extract from the CMakeLists.txt 

ADD_EXECUTABLE(testMapping testMapping.cxx) 

TARGET_LINK_LIBRARIES(testMapping ${ITK_LIBRARIES}) 

And the filter MapLR2HR is called from TestMapping.cxx. It used to work on a Linux system. 

Here is a stackexchange answer I found 

http://stackoverflow.com/questions/20230412/undefined-symbols-for-architecture-x86-64-shared-util-library-build-with-cmake 

So when I defined the function in the .h file itself the error disappeared. However, why this should happen for one particular function and not all the others. It should be consistent. So I am not able to figure that out. 

Thanks for all the help 

Vikash
