Chunhe Lee is still having a problem:
Johannes,

Thanks for the reply, I have rebuild dolfin according to what you said.
I think I have made some progress. Now both lapack and blas can be found
by dolfin. But it still can not find armadillo, I have set
armadillo=/home/rhome/lihe/bin/armadillo.

cmake -DARMADILLO_DIR:PATH=/home/rhome/lihe/bin/armadillo .
