无法解析链接错误

我需要在我的项目中包含代理库。一切都已成功安装。唯一的问题是，项目中有一个链接错误，我无法解决。

我正在工作的操作系统是Ubuntu 14.04。

这是错误日志：

在此处，库已成功添加，但无法将其链接到这些提到的标题。在线检查时，我发现我需要添加所需标头的二进制文件（也包括CPP）。

我的Cmake现在是：

cmake_minimum_required(VERSION 2.8)
project(string_from_url)
find_package(Boost COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})
set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_CURRENT_LIST_DIR}/build)
find_package( OpenCV REQUIRED )

set(SOURCE_FILES src/main.cpp)
add_executable(tutifruti ${CMAKE_CURRENT_LIST_DIR}/src/main.cpp src/CurlClient.cpp)

target_link_libraries(tutifruti opencv_objdetect)
target_link_libraries(tutifruti ${OpenCV_LIBS})
target_link_libraries(tutifruti ${Boost_LIBRARIES})

请在这里帮助我：/
