The python_orocos_kdl package have these lines in it's CMakeLists.txt: include(${CMAKE_SOURCE_DIR}/cmake/FindEigen2.cmake) > include_directories(${EIGEN2_INCLUDE_DIR}) It does not, however, have a rosdep entry in its manifest for eigen 2 or 3. Does this actually need eigen2 or can we safely update this to use eigen3, and shouldn't we add a to the manifest? If this can't be updated to eigen3, I need to go find an method for installing eigen2.
