Missing files in 0.4.0 LibOVR project

The project compiles correctly as a lib but trying to compile it as a DLL (like I did successfully with 0.3.x: https://developer.oculusvr.com/forums/viewtopic.php?f=20&t=7979) and I get linker errors with the LongPollThread class. The header file (Util_LongPollThread.h) is referenced but not included in the project. The implementation file (Util_LongPollThread.cpp) also exists but is not included in the project. When I include it though it has an undefined class: Watchdog. After commenting out the lines that use the watchdog, I'm able to successfully compile as a DLL.
