windows – Qt Creator使用MinGW编译器和CMake

我正在关注official guide,但它根本不起作用.这是我的步骤：

>将我的MinGW bin目录添加到PATH.
>运行QtCreator并设置CMake.
>打开一个非常基本的CMakeLists.txt文件.
>选择“Ninja(桌面)”作为CMake生成器.
>从CMake获取错误.

你可能已经注意到官方指南中根本没有提到第4步.我已经习惯了CMake,因此我问自己：

为什么Qt Creator不能提供正常的“MInGW Makefiles”生成器？

最后是最终的问题：

如何让Qt Creator通过CMake使用MinGW编译器？

回答的问题：

根据官方指南,正常情况下,正确设置PATH时,不应该执行步骤5.

为什么CMake没有在PATH中找到编译器集？

Ninja Generator会产生这些错误,如果你用CMake手动完成同样的事情就会发生.

Missing variable is:

  Tell CMake where to find the compiler by setTing the CMake cache entry
  CMAKE_C_COMPILER to the full path to the compiler,or to the compiler name
  if it is in the PATH.

查看配置菜单以查看我是否忘记设置某些内容,我偶然发现了编译器设置页面.我当然也在那里添加了我的编译器,但它没有做任何事情.

为什么CMake在使用CMake时不使用编译器列表？

它确实使用了编译器列表,如果您在套件选择中选择了正确的编译器.
