There is nothing in Eigen to link to your project: it's just headers
files to include. It's true that in Eigen 2.0 there was an option to
build a binary library containing some common instantiations, but we
removed that in the devel branch, and you shouldn't use it. Just unzip
the eigen archive and use the headers right away.
