如何在 visual studio 代码 MinGW 项目中包含 google 测试
How to include google test in visual studio code MinGW project
我正在 Windows 上进行 Visual Studio 代码项目，我想使用 Google 测试。只有当我尝试构建项目时，我才能包含头文件，我得到多个未定义的引用，可以在下面的错误列表中看到这些引用。
我已经将 Google Test 安装到 C:\googleTest。然后我 运行 在文件夹中执行以下命令：
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 task.json 参数中添加了以下内容。
"-l",
"gtest",
"-l",
"gtest_main"
导致此错误：

它似乎无法正确找到 google 测试库，但我不知道这是因为我忘记了某处的包含还是我不知道的步骤？
有人可以告诉我如何正确地将 google 测试添加到我的项目中并向我解释我在包含方面做错了什么吗？

类似于 -I（大写“eye”）表示在哪里可以找到包含文件，您需要一个 -L 表示在哪里可以找到库文件。
在 评论后我终于明白了：
我用mingw编译器以正确的方式重新编译了google测试库，如下图所示：
GoogleTest MinGW compiled
然后我修改了我的文件如下。
在 launch.json 文件中，我将 preLaunchTask 引用到我的“mingw 构建”，这使得在首次启动调试器时将执行此构建任务。请务必将您的 program.exe 正确引用到在构建任务中创建的 launch.json。这将 运行 调试器使用给定的可执行文件。
我还将我的 task.json 和所需的参数添加到 link myprogram 到构建 google 测试库和包含目录。
我现在可以使用 CTRL + SHIFT + B 构建，运行 使用 F5 调试程序。这与项目中包含的 google 测试库一模一样！

类似于 -I（大写“eye”）表示在哪里可以找到包含文件，您需要一个 -L 表示在哪里可以找到库文件。
在
我用mingw编译器以正确的方式重新编译了google测试库，如下图所示：
GoogleTest MinGW compiled
然后我修改了我的文件如下。
在 launch.json 文件中，我将 preLaunchTask 引用到我的“mingw 构建”，这使得在首次启动调试器时将执行此构建任务。请务必将您的 program.exe 正确引用到在构建任务中创建的 launch.json。这将 运行 调试器使用给定的可执行文件。
我还将我的 task.json 和所需的参数添加到 link myprogram 到构建 google 测试库和包含目录。
我现在可以使用 CTRL + SHIFT + B 构建，运行 使用 F5 调试程序。这与项目中包含的 google 测试库一模一样！
