使用 MinGW-64 构建 Qt 5.15.2：构建错误（缺少 EGL/egl.h）
Building Qt 5.15.2 using MinGW-64: Build Error (missing EGL/egl.h)
几天来我一直在尝试构建 Qt 5.15.2。我解决了几个问题，但我找不到太多关于最后一个错误（或已过时）的信息。
配置成功但使用 mingw32-make 命令构建失败并出现此错误：
qwindowseglcontext.h: 45: 10: fatal error: EGL / egl.h: No such file or directory
我知道它缺少 header，但我找不到关于如何更正此问题的可行解释。经过一些研究，我遇到了 https://cn.khronos.org/egl/ 但下载 link 已经死了，我还看到有人说可以使用 OpenGL ES AMD SDK，但我不知道它到底是什么。
如果有人能帮我解决这个问题，那将不胜感激。谢谢
