Cuda5 and CMake - cuda

Question

I have been working on getting some of the simple Cuda 5.0 samples to work on Windows 7 with CMake. I'm running Windows 7 64-bit and Visual C++ Express 2010.
I had this working the other day and now it fails to compile, and I'm not quite sure why. I generally do my coding in *nix environments so windows development environments aren't a strong area for me.
If anyone can help save me from pulling out more hair it'd be greatly appreciated.
The example is just the simple vectorAdd.cu file that comes with Cuda and a CMakeLists.txt file. In the interest of keeping this posting short I'll hold off on putting the source file up since it's a little long.
Here's my CMakeLists.txt file:
CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )
PROJECT( vectorAdd )
FIND_PACKAGE( CUDA REQUIRED )
CUDA_INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR} )
CUDA_ADD_EXECUTABLE( ${CMAKE_PROJECT_NAME} vectorAdd.cu )
When I try to compile, I get this output:

Anyone have a suggestion? I don't think I changed any settings from the time it worked to the time it stopped working. I've tried rebooting and all that stuff.
