CMake Linker:即使链接了库,也是未定义的引用

我正在使用CMake(CLion)进行课堂项目。我尝试了以下解决方案,但它们不起作用:123

我为一个类项目创建了一个HeapSort类,我需要使用它来对字符串向量(字典)进行排序。我在这个字典中创建了一个HeapSort类的实例,如下所示:

void Dictionary::heapSort()
{
    Heap<std::string> h;
    stringDict = h.heapSort(stringDict);
}

我不断获得构造函数和heapSort()函数的未定义引用,其中类定义如下(heapSort()类似):

Heap.cpp

#include "Heap.h"
template <typename T>
Heap<T>::Heap() {}

template <typename T>
void Heap<T>::initializeMaxHeap(std::vector<T> v)
{
    heap = v;
    heapSize = heap.size();
}

template <typename T>
void Heap<T>::maxHeapify(int i)
{
    int l = left(i);
    int r = right(i);
    int large;
    if (l <= heapSize && heap.at(l) > heap.at(i))
        large = l;
    else
        large = i;
    if (r <= heapSize && heap.at(r) > heap.at(i))
        large = r;
    if (large != i)
    {
        std::swap(heap.at(i), heap.at(large));
        maxHeapify(large);
    }
}

template <typename T>
void Heap<T>::buildMaxHeap()
{
    for (int i = std::floor(heap.size()/2); i > 1; i++)
        maxHeapify(i);
}

template <typename T>
std::vector<T> Heap<T>::heapSort(std::vector<T> v)
{
    initializeMaxHeap(v);
    buildMaxHeap();
    for (int i = heap.size(); i > 2; i++)
    {
        std::swap(heap.at(1), heap.at(i));
        heapSize--;
        maxHeapify(1);
    }
    return heap;
}

Heap.h

#ifndef PROJ3_HEAP_H
#define PROJ3_HEAP_H

#include <cmath>
#include <vector>

#include "Dictionary.h"

template <typename T>
class Heap
{
private:
    std::vector<T> heap;
    int heapSize;

public:
    Heap();
    int parent(int index) { return index/2; };
    int left(int index) { return index * 2; };
    int right(int index) { return index * 2 + 1; };
    int getItem(int index) { return heap.at(index); };
    void initializeMaxHeap(std::vector<T> v);
    void maxHeapify(int i);
    void buildMaxHeap();
    std::vector<T> heapSort(std::vector<T> v);

};


#endif //PROJ3_HEAP_H

的CMakeLists.txt

cmake_minimum_required(VERSION 3.6)
project(proj3)

set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp Dictionary.cpp Dictionary.h Grid.cpp Grid.h Heap.cpp Heap.h)
add_executable(proj3 ${SOURCE_FILES})

现在,我将所有文件放在一个文件夹中。我此时应该在CMakeLists.txt添加什么内容?我尝试add_library/target_link_library(使用不同的命令),添加include_directories,我尝试在我的目录中单独构建每个类,将它们链接到主可执行文件。我是否还需要重新组织我的目录?

编辑:添加了Heap.cpp&amp; Heap.h
