- For each supported platform:
- The name of the window system API
- The name of the window system specific context creation API, if applicable
- The names of the always supported context creation APIs EGL and OSMesa
- The names of the always supported context creation APIs and EGL
- Any additional compile-time options, APIs and (on Windows) what compiler was used
For example, compiling GLFW 3.5 with MinGW-64 as a DLL for Windows, may result
in a version string like this:
```c
3.5.0 Win32 WGL Null EGL OSMesa MinGW-w64 DLL
3.5.0 Win32 WGL Null EGL MinGW-w64 DLL
```
Compiling GLFW as a static library for Linux, with both Wayland and X11 enabled, may
result in a version string like this:
```c
3.5.0 Wayland X11 GLX Null EGL OSMesa monotonic
3.5.0 Wayland X11 GLX Null EGL monotonic
