I am trying to use some Eigen functionality in my code. I am on ros fuerte. I have looked at the ros eigen wiki. I have included the following in my Cmake:

find_package(Eigen REQUIRED)
include_directories(${Eigen_INCLUDE_DIRS})
include_directories(${Eigen_INCLUDE_DIRS})

as well as the following in my manifest:

  <rosdep name="eigen" />

but still have no luck.. I am receiving the fatal error that there is no such file or directory for Eigen/Dense.

Does anyone know what I might be missing or what other information you need to help pin down this problem?

I am very new to ROS and having some trouble getting past this.. Thanks in advance.
