There are packages for ROS in the aur. And there are wrappers for the commands needed to install packages from AUR. To install ros on my system I just need to execute pacaur -S ros-noetic-desktop-full In this case it will indeed compile the package with cmake. But there are also many binary packages on the aur. The user experience is not like Gentoo. I have never had problems finding a package with Arch.
