MinGw 无法从 cmake 编译测试文件

Question

我从官网安装了MinGW，我正在尝试编译一个简单的cmake项目。

我做到了

cmake -G"MinGw Makefiles" .

得到：

CMake Error at C:/Program Files/CMake/share/cmake-3.17/Modules/CMakeTestCCompiler.cmake:60 (message):
  The C compiler

    "C:/MinGW/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:

    Change Dir: C:/Users/LZ/Desktop/roosek_ocr/CMakeFiles/CMakeTmp

    Run Build Command(s):C:/MinGW/bin/mingw32-make.exe cmTC_3eeac/fast && C:/MinGW/bin/mingw32-make.exe -f CMakeFiles\cmTC_3eeac.dir\build.make CMakeFiles/cmTC_3eeac.dir/build

我找到了https://stackoverflow.com/a/55941909/6655884，但我查看了我的路径，但找不到sh.exe。最终我不知道它是否在那里。我该如何检查？在 powershell 上键入 sh，它抱怨它不是命令或脚本或任何东西。

其他帖子谈论通过巧克力安装的 MinGw，这不是我的情况。

这是 CMakeError.log：

我也遇到过这个问题，仍在寻找解决方案。我能够解决此问题的唯一方法是添加 CMAKE_CXX_COMPILER_WORKS=1 标志。
