[CMake] CMake can't find package on Windows

[Tron Thomas]

I am trying to use CMake to configure a project for Windows.  The 
project has dependencies on 3rd party packages.  Most of these packages 
are resolved successful with the FIND_PACKAGE command.  However, CMake 
is unable to resolve a recent package that was added to the project, 
even though the files for that package are located with the other 
packages CMake has been able to handle.

What can be done to determine why CMake is not finding this new package?
