Я получаю это при компиляции очень простого CMakeLists.txt

Похоже, что MinGW думает Я кросс-компиляции, хотя я не указал кросс-компиляции на моем CMakeLists.txt. Или он просто пытается что-то кросс-компилировать, но ошибка может быть в другом.
Я запускаю это на PowerShell. Я также попробовал cmd.exe. Он работает на оболочке MinGW64 из MSYS2, но это не относится к C:/MinGW/bin/g++.exe, и я не могу использовать эту другую оболочку, потому что она жалуется на то, что sw.exe находится в пути, и я не могу ее извлечь, потому что я должен запустить sw setup.
Как мне решить эту проблему?
