CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

一、报错描述：

用CMake构建c++程序时报错：

$ cmake .
-- Building for: NMake Makefiles
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.


CMake Error at CMakeLists.txt:2 (project):
  Running

   'nmake' '-?'

  failed with:

   系统找不到指定的文件。


CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

二、解决办法：

p.s. mingw64/bin和cmake已添加至环境变量中。

1. 编译时把

cmake .

改为：

cmake -G "MinGW Makefiles" .

2. 运行时使用：

mingw32-make.exe all

三、C++和cmake版本：

1. cmake-3.23.1-windows-x86_64.msi
2. mingw-w64-install.exe

系统：Windows 10
