CMake 找不到 Visual C++ 编译器

问题描述

在之前的项目上安装 Visual Studio 2015 并运行 CMake 后，CMake 错误表明它找不到 C 编译器.

After installing Visual Studio 2015 and running CMake on a previous project, CMake errors stating that it could not find the C compiler.

The C compiler identification is unknown
The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:4 (PROJECT):
  No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:4 (PROJECT):

我在 Visual Studio 文件夹 C:Program FilesMicrosoft Visual Studio 14.0 中搜索 cl.exe，但没有找到.

I went searching for cl.exe in the Visual Studio folder,C:Program FilesMicrosoft Visual Studio 14.0, and could not find it.

如何使用 Visual Studio 2015 设置 CMake 以在 Windows 上工作?

How do I set up CMake to work on Windows with Visual Studio 2015?

推荐答案

我找到了解决方案.虽然 Visual Studio IDE 安装成功，但它没有安装任何构建工具，因此没有安装 C++ 编译器.

I have found the solution. While the Visual Studio IDE installed successfully it did not install any build tools and therefore did not install the C++ compiler.

尝试手动在 Visual Studio 2015 GUI 中创建 C++ 项目 我能够提示它下载 C++ 包.然后 CMake 能够毫无困难地找到编译器.

By attempting to manually create a C++ project in the Visual Studio 2015 GUI I was able to prompt it to download the C++ packages. CMake was then able to find the compiler without any difficulty.
