I'm not new to programming, but I am new to building without an IDE doing all the work. Why is this failing?

Did you edit the CMakeLists.txt as explained at the very bottom of section 4.1 of the tutorial? You need to tell CMake which libraries you should link..

If you did follow this step and it does not work, please post your CMakeLists.txt.

@mig I added the CMakeLists.txt to the bottom of the original question. I'm thinking the issue may be that I don't have <visualization_msgs/Marker.h>. How can I verify that the Marker.h exists? I tried find /usr -iname "marker.h" and received nothing.

You don't have roscpp configured as a dependency, this is why you get all those linker errors to ros::.... This is, you didn't follow step 3 of the Tutorial correctly. You probably missed the roscpp part.

You need to add roscpp as a <build_depend> and a <run_depend> in the package.xml and in the find_package(catkin ... part in the CMakeLists.txt.

For more information, check out the catkin introduction here.

Also, ROS is installed in /opt/ros/<ROS_DISTRO>/, not in /usr.

I tried adding those nodes directly to the package.xml and it didn't work. I remade the package and violá. I can't believe I missed this. Thanks for your patience to show me my error, I really do appreciate that.
