ENV: ubuntu 22.04 | ros-humble | Eigen 3.4 | gtsam 4.2 from source(using system eigen)

In "gtsam 4.2", the author define in "Vector.h" as below:

38 typedef Eigen::VectorXd Vector;

which comflicted with the define in Eigen3.4-Eigen/src/core/Matrix.h

551 using Vector = Matrix<Type, Size, 1>;

This problem lead to a compile issues in "mapOptmization.cpp" - 1397 and 1401.
Change the Vector to Eigen::VectorXd can fix it
