Hi Alex, Seems I must unconciously have felt that LINK_INTERFACE_LIBRARIES had something to do with the problem of overlinking I'm trying to solve right now. Funny, this morning I came to the conclusion that I probably wouldn't need LINK_INTERFACE_LIBRARIES (see thread: [Q] LINK_INTERFACE_LIBRARIES and the like), and now it seems I will. Guess I'll have to study carefully how this whole import/export and interface libs stuff works. Could you point me to some examples?
