Cannot mix incompatible Qt library (5.15.15) with this library (5.15.14)

This happens on both master and develop branches with Jazzy; I haven't tested other distros. Other Qt ROS stuff like rqt works fine for example.

I don't know what the root cause of the problem is, but it seems that something in my system configuration sets the Qt environment variables to 5.15.15, while rviz2 in the overlay expects 5.15.14.

I set my system configuration to follow nixpkgs from nix-ros-overlay, but it doesn't make a difference.

I managed to work around the issue by patching the environment variables in my development shell as follows:

export QT_PLUGIN_PATH=`echo $QT_PLUGIN_PATH | sed 's/qt-5.15.15/qt-5.15.14/g'`
