为 VScode 配置 CMake raylib-cpp

Question

我已经在 VSCode 和 Notepad++ 中成功安装了 raylib 和运行示例 .c 文件。

我正在尝试执行此存储库中的文件 raylib-cpp/projects/CMake
我没有直接从 VSCoode 更改 repo 和运行 cmake 命令中的文件。
main.cpp

#include "raylib-cpp.hpp"
int main()
{
    int screenWidth = 800;
    int screenHeight = 450;
    raylib::Color background(RAYWHITE);
    raylib::Color textColor(LIGHTGRAY);
    raylib::Window w(screenWidth, screenHeight, "raylib [core] example - basic window");
    SetTargetFPS(60);
    while (!w.ShouldClose())
    {
        BeginDrawing();
        background.ClearBackground();
        textColor.DrawText("Success!", 190, 200, 20);
        EndDrawing();
    }
    return 0;
}

我尝试了运行这个 git 集线器仓库中指示的命令：raylib-CMake-example 但是当我从运行 make 命令时出现错误44=] bash 在 build 文件夹中，我也尝试了 mingw32-make 但它没有用。然后我在 VSCode
中安装了 CMake 工具扩展

和运行来自扩展的构建命令，但出现错误说明：
inline variables require at least '/std:c++17' [F:\Code\CPP\Raylib\TestGames\Game2CPP\build\raylib-cpp-example.vcxproj]

我正在使用 Visual Studio Build Tools 2017 Release-amd64 作为工具包。
当我尝试运行来自 raylib 的示例 .c 文件时，我不得不将 opengl 版本从 33 更改为 21 以使 window 正常工作。
我的文件夹如下所示：

输出日志如下所示：\

我看到已经报告了一个问题 https://github.com/RobLoach/raylib-cpp/issues/51。我猜作者的默认 C++ 编译器标准设置为 17，因此他的机器上没有问题。然而，你落后了一步。正如您的编译器所建议的那样，内联变量自 C++17 起可用。看来您使用的是一些较旧的标准（但不确定是哪个）。不确定哪个是 visual studio 的 cpp 编译器的默认编译器。

您可以像这样通过 CMake 为您的项目设置 C++ 标准：

set_property(TARGET tgt PROPERTY CXX_STANDARD 11)

考虑到这个库似乎是 'header-only'，您可以将 CXX_STANDARD 设置为 17 仅用于您的可执行文件。但是，如果该 raylib 库有一些对象，您必须在 https://github.com/RobLoach/raylib-cpp/blob/master/projects/CMake/CMakeLists.txt 中为 raylib-cpp-example 目标将 CXX_STANDARD 设置为 17。
