cudalegacy not compile -- nppiGraphcut missing

edit

trying to build v3.1 opencv with cuda support. standard cmake.
project of: opencv_cudalegacy and doing 'Build'

2 Problems:

• where are the identifiers for all the 'nppiGraphcut' symbols ?
• who or where is the command to link in opencv_cudalegacy310d.lib ? why is this being referenced here? i have searched and cannot find where this /L command is found.

thanks
