   ===============================================================
   Enabling the use of Eigen as a sparse linear algebra library 
   for solving the nonlinear least squares problems. Enabling 
   this option results in an LGPL licensed version of 
   Ceres Solver as the Simplicial Cholesky factorization in Eigen
   is licensed under the LGPL. 
   ===============================================================

-- Building without LAPACK.
