linking boost components - catkin error

edit

I followed most of the answers on how to link properly a library and still I cant compile my package with catkin_make, due to undefined reference to boost::log::v2s_mt_posix::trivial::logger::get()

Here is my the summary of my CMakeList.txt:

cmake_minimum_required(VERSION 2.8.3)
project(pleora_polarcam)

add_definitions(-std=c++11)

set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_FLAGS "-lboost_system") 
set(CMAKE_CXX_FLAGS "-lpthread")

find_package(catkin REQUIRED COMPONENTS
  roscpp
  cv_bridge
  image_transport
  dynamic_reconfigure
  driver_base
  camera_info_manager
)

find_package(OpenCV REQUIRED)
find_package(Boost 1.54 COMPONENTS log_setup log program_options thread REQUIRED)

catkin_package(
  INCLUDE_DIRS include

)

include_directories(
