一、开发环境搭建与配置 在开始之前c lass="tags" href="/C.html" title=c >c ;你需要配置好开发环境：
安装 SDL 库 ：c lass="tags" href="/C.html" title=c >c ;并借助包管理器 Conan 下载和安装 SDL 及其依赖项。这样可以避免手动构建和链接的复杂性【9】。
示例 CMake 配置 ：
<c lass="tags" href="/C.html" title=c >c ode c lass="tags" href="/C.html" title=c >c lass="prism language-c lass="tags" href="/C.html" title=c >c make">c lass="tags" href="/C.html" title=c >c make_minimum_required(VERSION 3.15)

target_link_libraries(game PRIVATE SDL2::SDL2-static lass="tags" href="/C.html" title=c >c )
class="tags" href="/C.html" title=c >c ode> 开发工具 ：推荐使用 Visual Studio 或 VS Code 作为 IDE。如果你在 Linux 或 mac lass="tags" href="/C.html" title=c >c OS 上开发c lass="tags" href="/C.html" title=c >c ;可以通过终端使用 <c lass="tags" href="/C.html" title=c >c ode>c lass="tags" href="/C.html" title=c >c makeclass="tags" href="/C.html" title=c >c ode> 编译和构建项目【9】【10】。
