使用 Cmake 和 Ninja 编译 Caffe 失败

Question

我尝试在启用 CMAKE_BUILD_SHARED_LIBS 选项的情况下在 windows 上编译 Caffe，但它失败了，并表示我需要使用 Ninja。当我在配置文件 (build_win.cmd) 和运行脚本中将 Ninja 设置为 1 时，它会抱怨并给出以下错误消息：

 CMake Error: CMake was unable to find a build program corresponding to
 "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select
 a different build tool. CMake Error: CMAKE_C_COMPILER not set, after
 EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after
 EnableLanguage
 -- Configuring incomplete, errors occurred! ERROR: Configure failed

我不知道我还需要采取哪些其他步骤才能成功完成编译过程。我所做的就是下载 Ninja，将其解压到某处并将其添加到我的环境变量中。

我还需要安装 gcc 吗？

更新

正如评论中所建议的那样，我检查了我的路径，发现它配置错误。我修复了现在出现这些错误，似乎找不到所需的库：

Answer 1

我找到了原因。我在我的系统上安装了 GCC，cmake 会尝试使用它而不是 Visual C++ 编译器。
所需要的只是下载 Ninja，将它放在你的路径变量中，你就可以开始了。
在 build_win.cmd 中更改所需的设置以使用 Ninja，您就完成了
