You need to run the batch script provided by Visual Studio to set up your environment before running cmake. It's under X:\Visual\Studio\Dir\VC\vcvarsall.bat. There should also be a shortcut in the start menu for "Visual Studio Command Prompt" that will open a prompt and automatically run vcvarsall.bat.
