Undefined reference to ros::xx even after linking to ${catkin_LIBRARIES} [closed]

edit

Hey everyone!

I'm pretty much used to ROS by now, but I got an error while catkin_make-ing a package that I can't really solve although it appears simple. I get all these errors while trying to link with the libraries:

and some more... The problem appears to be with the linker that doesn't identify the catkin libraries. However, inside my CMakeLists/txt I have the following:

add_executable(data_input_output src/data_input_output.cpp)
target_link_libraries(data_input_output ${catkin_LIBRARIES})
add_dependencies(data_input_output localization_gencpp)

add_library(field_model src/field_model.cpp) # adding the field_model as a library
target_link_libraries(field_model ${catkin_LIBRARIES})
add_dependencies(field_model localization_gencpp)

add_executable(particle_filter_localization src/particle_filter_localization.cpp)
target_link_libraries(particle_filter_localization ${catkin_LIBRARIES})
target_link_libraries(particle_filter_localization ${gsl_LIBRARIES} ${GSLCBLAS_LIBRARY})
target_link_libraries(particle_filter_localization field_model) #link ...
