Hi,

It looks like you're encountering two problems:

1) (The more important one) You're not linking in the ITKNumerics 
library, so you're getting linker errors about GradientDescentOptimizer 
and CostFunction. To fix this, I suspect (although I haven't tested it) 
that you need to find the line in your CMakeLists.txt file which looks 
something like this:

TARGET_LINK_LIBRARIES(${targetname} ITKAlgorithms ITKCommon ITKIO)

Then just add ITKNumerics to the end of that.

2) (The less important one) Microsoft has decided to warn you about 
using the Standard Library on security grounds -- this is somewhat 
understandable, but annoying (the replacement functions they want you to 
use aren't as portable as the standard ones). Most people I know seem to 
either ignore the warnings (they're an example of what people in 
comp.lang.c++ call "Microsoft silly warnings") or disable them by 
defining _SCL_SECURE_NO_WARNINGS (personally I recommend the latter, 
because if you've decided to ignore spurious warnings then you don't 
want them obscuring more important ones that you really need to deal with).

Regards,
Stu
