rviz does not build in noetic and melodicPython3

[lelongg]

rviz fails to build with the following error

-- Found PythonInterp: /nix/store/xcaaly5shfy227ffs8nipxrd49b56iqq-python3-3.10.8/bin/python3 (found suitable version "3.10.8", minimum required is "3.10")

reproducible with nix build github:lopsided98/nix-ros-overlay#noetic.rviz

There's not much I can do about this. The latest versions of Qt5 are no longer compatible with SIP 4, so I switched to Shiboken/PySide2 (see #224). This fixed rqt, but rviz is not compatible with PySide2, see: ros-visualization/rviz#1526

Thanks for maintaining all of the distros! Do you suggest anything that might help with building rviz?
edit: i ended up just compiling everything from an older commit, using the following inputs

      ros.url = github:lopsided98/nix-ros-overlay/6fa03dc558b92cf7f3a2d426c9335e014e3fd10d;
      ros.inputs.nixpkgs.follows = "nixpkgs";
      nixpkgs.url = github:nixos/nixpkgs/release-22.05;

I'm running into this too. Maybe we can pin rviz to an older version from nix-ros-overlay?

[natto1784]

Using this patch along with the old python-qt-binding override works with SIP4. I tested it as a global overlay for all distros and rviz compiled! Let's see if we can use this here for noetic and melodic specifically while using shiboken/pyside2 for other distros.
