我正在尝试构建一个 c 项目，我能够使用 cmake，它正在寻找 SDL。我还确认它是通过自制软件安装的，版本 2.26.3.
我在 macos Ventura 13.2.1 和 xcode 14.2 上使用 xcode 14.2 (14C18) 的命令行工具。在另一个 Stackoverflow 问题 中，他们提到这是一个没有安装 14.2 的问题，但我确认我已经安装了，但问题仍然存在。当我运行 make 时，出现以下错误：
[ 0%] Built target mgba-version-info
[ 44%] Built target mgba
[ 55%] Built target updater-stub

我四处搜索，没有找到太多关于可能是什么问题的信息。我还为 xcode 重新安装了最新的命令行工具，以防万一问题仍然存在。
我的问题是任何人都可以解释为什么 make 无法看到 SDL2，或者如何解决 macos 10.7 或更高版本的错误。我对 C 或 make 不够熟悉，无法理解如何解决 make 未看到的 SDL。
