NVCC not detecting modified header files for recompile

Working on a new project and I never noticed this before, but NVCC is not auto recompiling .cu files when included headers are changed in Visual Studio 2012 (anymore?)

Looking in Visual Studio tools options, I don’t see a setting to remedy this situation.

Using CUDA SDK 9.1 & Visual C++.

Can someone point out what I am missing? Thanks.

Turns out that Visual Studio will auto parse the included dependencies of .cu files.

But only if they are in the same folder, or include the path to the dependency file.

VS will not follow paths specified in the additional includes property settings.
