CMake Error at CMakeLists.txt:2 (include):

CMake Error at CMakeLists.txt:4 (rosbuild_init):
Unknown CMake command "rosbuild_init".

其實是因為ros的當前工作目錄沒設置對。

之前一直用

$ sudo gedit ~/.bashrc

把路徑加進去，後來source ~/.bashrc之後，還是找不對目錄。

然後

在/opt/ros/indigo/setup.sh最後加

export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/ORB_SLAM2/Examples/ROS

source 下成功了。 很神奇為啥在～/.bashrc下就不行

[ros]編譯ORBSLAM2時候，ros路徑問題
