环境：ubuntu18.04,g++9.5
编译时为什么出现
slam_in_autonomous_driving/src/tools/ui/ui_trajectory.h: In member function ‘void sad::ui::UiTrajectory::Clear()’:
/home/ubuntu/slam_in_autonomous_driving/src/tools/ui/uitrajectory.h:29:14: error: ‘struct pangolin::GlBuffer’ has no member named ‘Free’
29 | vbo.Free();
可是我看了GlBuffer这个结构体是有Free这个成员函数的啊，它继承了GlBufferDate，这个函数有，请教，安装搞了好久
