解决【Windows】下CMake不能生成makefile的问题

遇到这个问题的场景是：

PS C:\Users\Administrator\Desktop\Cplus\test\build> cmake ..  
-- Building for: Visual Studio 16 2019
-- Selecting Windows SDK version 10.0.18362.0 to target Windows 10.0.19042.

PS C:\Users\Administrator\Desktop\Cplus\test\build> make      
make: *** 没有指明目标并且找不到 makefile。 停止。

然后生成了一堆？？？

然而我想要的是带有makefile文件的那种，之前是在ubuntu上跑的那种

发现了问题

可能是由于我之前安装了Visual Studio 2019，也或者是windows10默认，我并没有去探究具体的

so,CMake会生成MSVC解决方案。在构建目录中检查 .sln 文件。

可以看到上图就有.sln结尾的文件

解决方法

指定解决方案是Unix 平台的Makefiles

cmake .. -G "Unix Makefiles" （第一次运行cmake时）

后面就直接cmake ..

PS C:\Users\Administrator\Desktop\Cplus\test\build> cmake ..  -G "Unix Makefiles" 
-- The C compiler identification is unknown
-- The CXX compiler identification is GNU 10.2.0
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done

-- Detecting CXX compile features

This is a test file!

可以看到这就是我想要的，完美解决！！！
