ROS编译报错
运行catkin_make后，出现报错，求解决方案catkin_make -DCATKIN_WHITELIST_PACKAGES="navigation-melodic"
Base path: /mnt
Source space: /mnt/src
Build space: /mnt/build
Devel space: /mnt/devel
Install space: /mnt/install

CMake Error: The current CMakeCache.txt directory /mnt/build/CMakeCache.txt is different than the directory /home/wheeltec/wheeltec_robot/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source "/mnt/src/CMakeLists.txt" does not match the source "/home/wheeltec/wheeltec_robot/src/CMakeLists.txt" used to generate cache.Re-run cmake with a different source directory.
Invoking "cmake" failed
1.navigation_melodic不是功能包的名字哈，您点开这个文件夹会看到里面的文件夹才是功能包
2.请不要在虚拟机或者实体电脑端，在挂载的目录下面编译功能包，这样是不行的，需要ssh登陆到小车，到小车的工作空间下编译
