title: load shared lib in GDB session
body: <p>I have a binary that depends on a certain shared lib and when I try to run the binary under GDB, it says that this shared lib is not found: <code>error while loading shared libraries: libshr1.so: cannot open shared object file: No such file or directory</code></p>
  <p>How can I tell to GDB where this library is located and load it? I am looking for something similar to <code>LD_LIBRARY_PATH</code>, but I want to set it directly from the GDB session.</p>
