CUDA MINING

I tried to do the following , but it is not working

Building on Windows

download or clone this repository
download and install Visual Studio 12 2013 and CMake
run getstuff.bat in cpp-ethereum/extdep
open a command prompt and navigate to cpp-ethereum directory
mkdir build
cd build
cmake -DBUNDLE=cudaminer -G "Visual Studio 12 2013 Win64" ..
if you don't want/need CUDA support, use "miner" instead of "cudaminer". This will only compile OpenCL support
to speed up compilation a bit, you can add -DCOMPUTE=xx , where x is your CUDA GPU Compute version * 10. i.e -DCOMPUTE=52 for a GTX970.
you may disable stratum support by adding -DETH_STRATUM=0
When CMake completes without errors, opn ethereum.sln created in the build directory in Visual Studio
Set "ethminer" as startup project by right-clicking on it in the project pane
Build. Run

the error I am getting is when I type this
cmake -DBUNDLE=cudaminer -G "Visual Studio 12 2013 Win64" ..
