Basically the equivalent of > LDFLAGS += -lsomelib The GNU runtime dynamic library will honor DT_NEEDED flags of libraries, too. That is, you can just do LDFLAGS += -lsomelib on a library target and it will work. Check libgtk-3.so, for instance:
objdump -x /usr/lib/x86_64-linux-gnu/libgtk-3.so will show a bunch of lines like... Dynamic Section: NEEDED libgdk-3.so.0 NEEDED libgmodule-2.0.so.0 NEEDED libpangocairo-1.0.so.0 NEEDED libX11.so.6 NEEDED libXi.so.6 NEEDED libXcomposite.so.1 NEEDED libXdamage.so.1 (...) Meaning, all these libraries need to be loaded for libgtk-3.so to work. Beware gotchas: - Not all rtdl implementations do so, so if you're not using a GNU platform (e.g., Linux), then check the documentation of your runtime dynamic linker. - This works for shared libraries, but not for static ones.
