我使用 Premake 来管理项目的构建配置，该项目由两个静态库（“Engine”和“Game”）和一个可执行文件（“Launcher”）组成。但是当我尝试将 GLFW 集成/链接到我的引擎库时，我遇到了链接错误。
我应该提到我正在尝试静态链接 GLFW。我还在 Windows 平台上使用 Visual Studio 2022。

我刚开始使用 Premake，所以我不完全确定我做错了什么。我注意到一些开发人员将 GLFW 直接作为项目集成到他们的解决方案中，但如果可能的话，我想避免这种情况，因为我计划在将来添加其他库并希望避免膨胀。
看来链接多线程版本的 GLFW (glfw3_mt) 而不是标准版本 (glfw3) 解决了问题。
