thanks. that helped a lot.  the interesting thing is i had already checked the /Zc:wchar_t- setting in the visual studio build settings, and both projects had that turned off... but i was still getting the linker errors.  yanking that out of the CMakeLists.txt file and recreating the visual studio solution in cmake fixed it though.

It's probably this issue -
