LINK_LIBRARIES() applies solely to targets defined *later*, i.e. foo won't link against subA, but in return, all later targets will do even if this isn't necessary. Thus, TARGET_LINK_LIBRARIES(foo subA) probably suits better to express foo's need to be linked against subA. Moreover, it tracks mediate dependencies automatically, e.g. if subA depends on, say, subAA, then foo will be linked to subAA, too, although there has not been a TARGET_LINK_LIBRARIES(foo subAA). Finally, LINK_LIBRARIES() is considered as obsolete; in fact, the CMake 2.6 documentation does not regularly mention it anymore, and in 2.4, it's denoted "old".
