C++ 无法在我的CLion（CMake）项目中导入google测试

我试图在我的CMake项目中使用Google测试，但没有成功

我遵循了官方《CLion指南》上的说明：

现在我的项目树是这样的：

main_project_folder
|__lib/
|__src/
|__Google_tests/
|  |__googletest/        <-- (downloaded from official googleTest repository)
|  |__test1.cpp
|  |__CMakeLists.txt
|__CMakeLists.txt
|__main.cpp
|__Makefile

这就是test1.cpp的样子：

   #include "gtest/gtest.h"
    
    TEST(test,test1){
        EXPECT_TRUE(1);
    };

在我的main

CMakeLists.txt的底部，我还添加了

enable_testing()
add_subdirectory(Google_tests)


问题是，当我构建项目时，我从编译器那里得到了一长串错误，所以我不能继续学习教程。
（CMake项目的其余部分，不包括GoogleTest的完美构建）。此外，重新加载CMake项目不会返回错误。
我做错了什么

以下是我收到的（部分）错误：
