Uppercase windows.h include fails build in case-sensitive OS #6365
Description
Line 26 in 22f3825
When cross-compiling v1.5.0 with MinGW-w64 on Linux, I'm running into an error:
src/libgit2-1.5.0/src/cli/opt.c:26:11: fatal error: Windows.h: No such file or directory
26 | # include <Windows.h>
| ^~~~~~~~~~~
compilation terminated.
It should be all-lowercase windows.h.
