catkin_make failed

[donghs1234]

make other files is common when i run catkin_make on this project,it remind me "CMake Error at /opt/ros/melodic/share/catkin/cmake/catkin_workspace.cmake:95 (message): This workspace contains non-catkin packages in it, and catkin cannot build a non-homogeneous workspace without isolation. Try the 'catkin_make_isolated' command instead. Call Stack (most recent call first): CMakeLists.txt:67 (catkin_workspace)
