Most of the readily available documentation for installing / using Orocos is out of date. For example, that page you were at is (at timeof writing) 6 years old, for an end-of-life distro.

The up-to-date info is on their github and website (The website, for you right now, is probably less useful, but this page still is). Respectively, you should now install that fat stack as sudo apt install ros-melodic-rtt-ros-integration, aka install from binary sources. Make sure to pay careful attention to Building ROS-Based Orocos Components, because they have their own system which changes the CMake process. There's also other packages that they/others keep from other stacks, you can see the whole list by trying to autocomplete apt install ros-melodic-rtt-
