DSO_ROS编译提示“dso_live”SET TO NOTFOUND

1 在安装完成DSO之后，如果需要用到自己的设备跑DSO的话，需要安装DSO_ROS,https://github.com/JakobEngel/dso_ros,下载

2 在编译过程中提示

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
DSO_LIBRARY
    linked by target "dso_live" in directory /home/peter/catkin_ws_dso_ros/src/dso_ros-catkin

3 提示“dso_live”这个库文件找不到。打开dso ros的camkelist，下图最后一行发现要对已经装好的DSO进行路径设置，这样dso ros才可以找到dso的库文件。

4 根据cmakelist的提示，DSO_PATH是dso编译文件中，build的上级所有目录，即export DSO_PATH=/home/peter/catkin_ws_DSO/dso-master

5 再次catkin_make成功，如图
