Lorenz, I'm sorry but you're answer both version of them are giving another error:

CMakeFiles/epsilon_node_1.dir/src/epsilon_node_1.o: undefined reference to symbol 'boost::system::system_category()'


I've already had problems with boost in this project, which I've solved according to the solution in that question and I've expanded it into:

target_link_libraries(epsilon_node_1 ${Boost_FILESYSTEM_LIBRARY}${Boost_SYSTEM_LIBRARY} ${Boost_BIND_LIBRARY})  But this doesn't solve the problem, do you know by any chance the name CMake needs for the bind to work?
