BUG: Fix py_nomainwindow_DCMTKPrivateDictTest on Windows
requested to merge github/fork/msmolens/fix-py_nomainwindow_DCMTKPrivateDictTest-windows into master
Created by: msmolens
Test py_nomainwindow_DCMTKPrivateDictTest fails on Windows because DICOMLib can't find the dcmdump.exe utility.
Based on a comment in DICOMProcesses.py, the DCMTK build tree didn't always include the configuration name (i.e. 'Debug' or 'Release') in the build path for the utilities. Now the build tree does include the configuration name. This commit adds the 'Debug' and 'Release' subdirectories to the list of searched paths.
Fixes #4049
