Unable to Launch Debugger in VS2015 running OpenCL Samples

I've downloaded and successfully run the code samples from the Intel OpenCL website under "Release" configuration.

(for example, Sobel, CapsBasic, and others).

So, I'm confident that my SDK/drivers setup is mostly working.

However, I'm not able to launch these examples in "debug" mode (to set breakpoints, step through code).  When I run with debug, I am told that a dependant dll is missing.  Here is the full output from a debug/win32 session when I click "Local Windows Debugger":

'CapsBasic.exe' (Win32): Loaded 'C:\_CVWork\OpenCL\intel_ocl_caps_basic_win\CapsBasic\Win32\Debug\CapsBasic.exe'. Symbols loaded.'CapsBasic.exe' (Win32): Loaded 'C:\Windows\SysWOW64\ntdll.dll'.

Symbols loaded.The program '[11500] CapsBasic.exe' has exited with code -1073741515 (0xc0000135) 'A dependent dll was not found'.

To clarify, I do have the API debug options set in the Code-Builder->Open CL Debugger->Options... window ("Enable OpenCL kernel debugging for CPU device" box is checked, as is "Enable remote OpenCL kernel debugging for GPU device").

Appreciate any insight on how to get breakpoints / debug runs working with the sample code using VS2015.
