the eigen library cmake namespace and name is
Eigen3::Eigen
not Eigen3::eigen
this needs to be changed in the generated use script, not that anything I know of is using EIGEN_LIBRARIES... we use the name of the library (Eigen3::Eigen) directly
eigen was recently modified to be built via cmake, instead of just copying the headers (it's a header-only library), in using the upstream project's cmake, I decided not to override the namespace or name of the library (was xpro::eigen before the last externpro release)
