解决方法：

用locate命令定位XXX库文件

locate libpose_utils.so

得到结果为：

/home/labh/.local/share/Trash/files/Fast-Perching/devel/lib/libpose_utils.so
/home/labh/.local/share/Trash/files/devel.2/.private/pose_utils/lib/libpose_utils.so
/home/labh/.local/share/Trash/files/devel.2/lib/libpose_utils.so

再用软链接将上述中的任意一个与其链接起来

sudo ln -s /home/labh/.local/share/Trash/files/devel.2/lib/libpose_utils.so /usr/lib/libpose_utils.so
