llvm and clang: trying to "cmake" a "Visual Studio 10"

HI,

I AM USING CMAKE TO TRY TO GENERATE MY
CMAKE CMakeFiles FOLDER AND CMakeCache.txt FILE.

I AM RUNNING THE FOLLOWING COMMAND.

"F:\Program Files\CMake 2.8\bin\cmake" -G "Visual Studio 10"
M:\YDrive\All_Economics\eclipse_workspace\CheckoutLLVM\llvm

HERE ARE MY RETURNED MESSAGES.

The CXX compiler identification is unknown
