我在项目中链接libmongocxx时遇到问题。

我正在使用CMAKE链接库，我正在运行Ubuntu 17.10。

这是我的CMakeLists.txt：

    cmake_minimum_required(VERSION 3.9)
    project(web_service_cpp)

    SET(CMAKE_CXX_STANDARD 14)

    set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
    set(LIBRARY_OUTPUT_PATH  ${CMAKE_BINARY_DIR}/lib)

    find_package(Boost REQUIRED)
    find_package(Hana REQUIRED)
    find_package(libmongocxx REQUIRED)
    find_package(libbsoncxx REQUIRED)
    add_library(libmongocxx INTERFACE IMPORTED)
    set_property(TARGET libmongocxx PROPERTY
    INTERFACE_INCLUDE_DIRECTORIES ${libmongocxx_INCLUDE_DIR})

    add_library(boost INTERFACE IMPORTED)
    set_property(TARGET boost PROPERTY
    INTERFACE_INCLUDE_DIRECTORIES ${Boost_INCLUDE_DIR})

    include_directories(${LIBMONGOCXX_INCLUDE_DIR})
    include_directories(${LIBBSONCXX_INCLUDE_DIR})
    include_directories("/usr/local/include/mongocxx/v_noabi")
    include_directories("/usr/local/include/bsoncxx/v_noabi")
    include_directories("/usr/local/include/libmongoc-1.0")
    include_directories("/usr/local/include/libbson-1.0")
    include_directories("/usr/local/lib")

    include_directories("${PROJECT_SOURCE_DIR}")
    set(SOURCE_FILES src/main.cpp
            src/cMqttService.cpp
            src/cMongoDB.cpp
            src/cRepository.cpp)


    set(HEADER_FILES include/cRepository.h
                include/cMqttService.h
                include/cMongoDB.h
                include/main.h)


     add_executable(web_service_cpp
            ${HEADER_FILES}
            ${SOURCE_FILES})

    target_link_libraries(web_service_cpp ${LIBMONGOCXX_LIBRARIES})
    target_link_libraries(web_service_cpp ${LIBBSONXX_LiBRARIES})

我发现我收到此错误很奇怪，因为它用于处理macOS：

我找到了解决问题的方法。它是由我在macOS上使用的所有硬编码字符串引起的。
