Hi Gilles,

The error message from CMake is a little bit cryptic, but what it is
trying to say is that the library itself could not be found; therefore,
specify -D ARMADILLO_LIBRARY=/usr/local/lib/libarmadillo.so (or whatever
the location of the actual library is).  The version of Armadillo you
have is just fine.

Thanks,

Ryan
