我正在尝试使用visual studio 2012（版本10.0）构建LLVM。我安装了CMake并运行了以下命令：
运行这些命令可以正常工作，直到最后一步。我收到了大量的警告（？），如下所示：

这些文件存在于我的系统下的C：\ Program Files（x86）\ Microsoft Visual Studio 10.0 \ VC \ include下。该命令已完成，但尚未生成文档告诉我应创建的LLVM.sln文件。
有人可以建议如何纠正我遇到的问题吗？我很感激您提供的任何指导。

cmake visual studio 10驱动程序适用于visual studio 2010. http://www.cmake.org/cmake/help/v3.0/generator/Visual%20Studio%2010%202010.html
LLVM和clang需要一个可以完成大多数c ++ 11事情的编译器。
答案 1 :(得分：1)
您需要将Visual Studio放在路径上。在调用CMake之前，必须从命令行运行批处理文件vcvars32.bat（对于32位编译）或vcvars64.bat（对于64位编译）。这将设置所有路径和其他环境变量，以便编译器可见。＆＃34;
在您的系统上，它们位于
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat
和
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64\vcvars64.bat
