title: Whether the directory set by "LD_LIBRARY_PATH" will find its subdirectory?
body: <p>I want to run a c++ code with lib.so and set the "LD_LIBRARY_PATH=/apollo/bazel-bin" but the lib.so is in "/apollo/bazel-bin/python", then I got the error can't find the lib.so.<br>
  Whether the directory set by "LD_LIBRARY_PATH" will find its subdirectory? I have some lib.so in "/apollo/bazel-bin/a" "/apollo/bazel-bin/b" and "/apollo/bazel-bin/c", I don't want to set 3 dir but "/apollo/bazel-bin/"?</p>
