But I had not realised that the old installed libs were the problem.
Another reason to build qt in /opt.
I start my qt5 script with:
export QT5PREFIX=/opt/qt5
sudo rm -rf /opt/qt-$VERSION $QT5PREFIX
sudo mkdir -p $QT5PREFIX
Since I have now:
lrwxrwxrwx 1 root root 9 Aug 20 17:07 qt5 -> qt-5.11.1
drwxr-xr-x 14 root root 4096 Aug 26 13:40 qt-5.11.1
$ echo $PATH
...:/opt/qt5/bin:...
Removing the $QT5PREFIX symlink allows the new build (e.g. 5.12.0) to
populate a new directory and the system can't find the old version.
If I have a problem with the new version, I just recreate the old symlink.
