title: Several subprojects. duplicate symbols for architecture
body: <p>I have a workspace with several projects of reusable artifacts, which are compiled into static libraries. Later, I'm using these libraries in other projects by including them as a sub-projects by reference. But I've faced problem of "duplicate symbols" when project A uses libraries B and C, which are both using library D (libraries B and C included as a sub-projects to project A, and all libraries B,C,D are from artifacts workspace). How can I solve this problem? </p>
