我正在做一个Windows上的Visual Studio代码项目，我想使用Google Test。我只能包含头文件，当我尝试构建项目时，我得到了多个未定义的引用，可以在下面的错误列表中看到这些引用。

我已经在C:\googleTest中安装了Google Test。然后，我在文件夹中运行了以下命令：

cmake .
cmake --build .
navigated to the googletest\googletest\gtest.sln 
And build this with the help of Visual Studio i build the solutions by pressing build all under build menu.

我尝试过的:我在我的task.json参数中添加了以下内容。

                "-l",
                "gtest",
                "-l",
                "gtest_main"

这导致了这个错误：

它似乎不能正确地找到google测试库，但我不知道这是因为我在什么地方忘记了一个include，或者可能是我没有意识到的一个步骤？

谁能告诉我如何正确地将google test添加到我的项目中，并向我解释一下我在includes中做错了什么？

在rveerd's评论之后，我终于弄明白了：

我用mingw编译器以正确的方式重新编译了googletest库，如下图所示：

GoogleTest MinGW compiled

然后我修改了我的文件，如下所示。

在launch.json文件中，我将preLaunchTask引用到我的"mingw build“，这使得在第一次启动调试器时，这个构建任务将被执行。确保正确地将您的program.exe引用到在build任务中创建的launch.json。这将使用给定的可执行文件运行调试器。

我还添加了带有所需参数的task.json，以便将我的程序链接到构建的google测试库和include目录。

我现在可以使用CTRL + SHIFT +B进行构建，并使用F5在调试中运行程序。这与项目中包含的google测试库是一致的！

类似于-I (大写的“眼睛”)，它告诉你在哪里可以找到包含文件，你需要一个-L来告诉你在哪里可以找到这些库。
