推荐答案

在CMake-gui中：选择源&二进制文件夹，然后单击配置，它将询问您要使用哪个版本的编译器。确保选择了正确的

In CMake-gui: After you selected the source & binary folder and click "configure" it will ask you which version of the compiler to use. Make sure that you select the correct one

例如，如果您安装了 Visual Studio 2015并选择了 Visual Studio 2017，则会遇到无法运行MSBuild命令：错误。

For example, if you have "Visual Studio 2015" installed and you select "Visual Studio 2017", you will run into the "Failed to run MSBuild command:" error.

如果确实选择了错误的选项，则删除二进制文件文件夹或直接使用其他二进制文件文件夹-然后单击配置。然后选择正确的编译器。

If you did select the wrong one, either delete the binaries-folder or simply use another binaries-folder - and then click configure and select the correct compiler.
