I don't remember exactly how to do this, but I think that when you
compile Armadillo, you may have to tweak the compilation settings so
that the .lib is generated. I'm sorry I can't provide better advice
than that; it seems like my Windows build slaves are broken right now
(typical) so I can't even test it without putting hours into debugging
stupid, overly complex compiler setup issues. :(
The process may be different with MinGW/MSYS anyway, so I'm not sure how
helpful I can be there since I don't have that set up.

Can you attach the config.hpp file from Armadillo, the CMakeCache.txt
from the Armadillo build, and also the (partially) generated
CMakeCache.txt from the mlpack configuration?

You can set CMAKE_INSTALL_PREFIX at configure time to set where it gets
installed, assuming that Armadillo plays nice with that (which... it
should, hopefully).
