Cannot run in windows; libmcfgthread-1.dll was not found about raylib-go

Not related to raylib/raylib-go. That has everything to do with your toolchain, i.e. old MinGW, broken install, etc. You didn't mention what C compiler are you using.

You can also compile a static binary, i.e.:

$ CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go build -ldflags "-s -w '-extldflags=-static'"
$ file basic_window.exe
basic_window.exe: PE32+ executable (console) x86-64 (stripped to external PDB), for MS Windows, 11 sections

Anyway, even without -extldflags=-static the binary should work without dependencies, try using TDM-GCC, in Windows that one always just worked for me.
