Question

我想在我的 CMake 项目中使用 Vulkan 我应该如何进行？

查看 Vulkan 示例并不能真正揭示如何做事。并且许多教程坚持要求您修改自己的环境以使其正常工作。

理想情况下，我只希望它可以轻松工作，而不必担心包含目录/链接。

Answer 1

这就是 CMake 和开源的美妙之处。

我在示例中使用的是 Windows/Visual Studio 2019，但这并不重要。

首先下载 Vulkan SDK：https://www.lunarg.com/vulkan-sdk/

重新启动计算机以确保安全（环境变量）。 VulkanSDK 将环境变量放入您的系统。（我意识到您在技术上不必重新启动计算机，但我不想提供有关环境变量的速成课程）

现在我们可以进入 CMake。

cmake_minimum_required(VERSION 3.19)

project(EXAMPLE
    LANGUAGES CXX
)

find_package(Vulkan REQUIRED)

add_executable(foobar)

target_sources(foobar PRIVATE main.cpp)

target_link_libraries(foobar PRIVATE Vulkan::Vulkan)

这就是我的 main.cpp 的样子

#include "vulkan/vulkan.h"
#include <iostream>

int main()
{
    std::cout << "Hello World\n";
}

这是我的 CMake 构建命令的样子：
