Error after modifing crazyswarm_server.cpp

[a240160572]

I made modifications in src/crazyswarm_server.cpp, only on the logging frequency.

Now, I have the following error after I run the launch file (already sourced before):
ERROR: cannot launch node of type [crazyswarm/crazyswarm_server]: Cannot locate node of type [crazyswarm_server] in package [crazyswarm]. Make sure file exists in package path and permission is set to executable (chmod +x) ERROR: cannot launch node of type [crazyswarm/crazyswarm_teleop]: Cannot locate node of type [crazyswarm_teleop] in package [crazyswarm]. Make sure file exists in package path and permission is set to executable (chmod +x)

Both files are executable from cmake file:
`add_executable(crazyswarm_server
src/crazyswarm_server.cpp
)
target_link_libraries(crazyswarm_server
${catkin_LIBRARIES}
)

add_executable(crazyswarm_teleop
src/crazyswarm_teleop.cpp
)
target_link_libraries(crazyswarm_teleop
${catkin_LIBRARIES}
)`

I tried to re-make the crazyswarm package but the make fails
`CMake Error at /opt/ros/melodic/share/catkin/cmake/assert.cmake:20 (message):

Can anyone help with that or what is the correct way to modify the src? Thank you

1. Modify the source
2. Run catkin_make in ros_ws
3. Fix any build erros
