Subject: [PATCH 1/2] Use CMake to build Eigen3

Since 3.3.3, Eigen has included an INTERFACE target. Use CMake to build Eigen so the generated target can be imported in your project using `target_link_libraries` rather than having to distribute `FindEigen3.cmake` with your project.

    find_package(Eigen3)
    target_link_libraries(myproject Eigen3::Eigen)
