undefined reference to `boost::system::generic_category()' when adding boost/asio

I want to use boost.asio header in my project, but when I include it's .hpp file I got this output error on compile:

• I need boost.asio for crow to route my web request.

I'm using CLion 1.2.4 as IDE this is my main.cpp content:

#include <iostream> #include <boost/asio.hpp> using namespace std; int main() { cout << "Hello, World!" << endl; return 0; } 

And this is my CMakeLists.txt file content:

cmake_minimum_required(VERSION 3.3) project(rcp) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -lboost_system") set(SOURCE_FILES main.cpp) set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/bin") include_directories("libraries/boost") add_executable(rcp ${SOURCE_FILES}) 

Thank you so much
