我使用 CMake 2.8.9 得到以下错误：
CMake Error: CMake was unable to find a build program corresponding to "Visual Studio 11 Win64". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: Could not find cmake module file:H:/ogredeps/CMakeFiles/CMakeCCompiler.cmake
CMake Error: Could not find cmake module file:H:/ogredeps/CMakeFiles/CMakeCXXCompiler.cmake
Configuring incomplete, errors occurred!
我在 Windows 7 64 上使用 Visual C++ 2012 Express。
我究竟做错了什么？
