C++ Boost filesystem library compilation error - c++11

Question

I am new to c++ and I am using CLion on a Mac. I would like to use the boost 1.65.0 filesystem library. When I add the following import statement the console app doesn't compile.
#include <boost/filesystem.hpp>
I get the following error:
Undefined symbols for architecture x86_64:
"boost::system::system_category()", referenced from:
___cxx_global_var_init.2 in main.cpp.o
"boost::system::generic_category()", referenced from:
boost::system::error_category::std_category::equivalent(int, std::__1::error_condition const&) const in main.cpp.o
boost::system::error_category::std_category::equivalent(std::__1::error_code const&, int) const in main.cpp.o
___cxx_global_var_init in main.cpp.o
___cxx_global_var_init.1 in main.cpp.o
ld: symbol(s) not found for architecture x86_64

CMake file:
cmake_minimum_required(VERSION 3.8)
project(sandbox)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES src/main.cpp)
find_package(Boost)
if (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIR})
endif()
add_executable(sandbox ${SOURCE_FILES})
target_link_libraries (sandbox ${Boost_LIBRARIES})
Other libraries such as the boost string library works fine. But I cant use the filesystem library. Any idea what I am doing wrong?
