日安。在不使用cmake“”g++ -lpthread src/how2thread.cpp src/main.cpp -ggdb 3-std=c++17 -Wextra“”的情况下编译程序不会产生错误。但是，使用“”cmake . && make“”会产生以下编译错误：

我在头文件中指定data_arr_protect是std：：mutex对象，

class Scheduler
{
// class for schedule slicers, processors and collecting data
public:
    Scheduler(const std::vector<char>& data,
              const std::string& mask); // construct and parse data
    Request get_request(); // used to get another batch
    void write_request(Request&&);

    void write_finding(Finding&& find);

    using Find_it = decltype(std::declval<std::vector<Finding>&>().cbegin());
    Find_it cbegin();
    Find_it cend();

    const auto& get_slicing_status(){return is_slicing;} //
    std::string mask;

# ifndef DEBUG_V

private:

# endif

    const size_t slicer_num;
    std::queue<Request> data_arr; // consider switching to deQ
    std::mutex data_arr_protect;//for mt rw to vec // might be switching to semaphores

    std::queue<Actor_processor> proc_instances_q;
    std::queue<Actor_slicer> slicer_instances_q;

    std::vector<Finding> result_arr;
    std::mutex result_protect;//for mt write to vec

protected:
    friend class Actor_slicer; // we need access from slicers to mutexes as they're pretty lowlvl
    std::vector<std::mutex> char_segments_protect;
    std::vector<size_t> finish_line_no;
    std::atomic<size_t> is_slicing; // for break cond 
};

我cmake文件看起来

cmake_minimum_required(VERSION 3.10.0)
project(how2thread
        VERSION 0.0.1
        DESCRIPTION "simple mt parser app"
        LANGUAGES CXX)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)

file(GLOB_RECURSE src_files src/*.cpp)

add_library(how2thread_lib src/how2thread.cpp src/how2thread.hpp)

add_executable(how2thread src/main.cpp)
target_link_libraries(how2thread PRIVATE how2thread_lib)
target_link_libraries(how2thread PRIVATE Threads::Threads)

什么会导致编译器的误解，我必须如何修复它？
我尝试了不同的链接选项，比如用main.cpp文件构建我的how2thread.cpp文件，尽管它没有帮助。而且我没有得到关于未定义类或其他东西的错误，所以，我猜，头文件被包含在.cpp文件中
