cant help with LAPACK, but adding Eigen support should be as easy as:
- download : http://eigen.tuxfamily.org/ and unzip
(it is a “headers only” lib, no “install” needed) - WITH_EIGEN=ON (cmake)
- EIGEN_INCLUDE_PATH=/path/to/Eigen_toplevel_folder (cmake)
carefully observe the cmake output,
it should show up under " Other third-party libraries:"
