Make sure you build the "no debug" version of wxWidgets and then make
sure that you select the following:

wxWidgets_CONFIGURATION == mswu (msw unicode non-debug)

and

wxWidgets_USE_REL_AND_DBG == TRUE

You might need to remove the CMakeCache for this.

Probably just picking up a ms visual c++ dll in the system.

I'll add whatever is needed to the FindwxWidgets after we fix everything.
