Where did you install Armadillo?  /usr/local/lib and
/usr/local/inclukde?  Or maybe you forgot to type 'make install'?

Regardless, you can specify the location of libarmadillo.so and the
include directories and it will work:

$ cmake -D ARMADILLO_LIBRARY=/path/to/libarmadillo.so -D ARMADILLO_INCLUDE_DIR=/path/to/armadillo/include/ ../

Note that the Armadillo include directory is not armadillo_bits/ but
instead the directory containing the armadillo header file.

Hope this helps. :)
