I'm having issues when deploying my app to some Ubuntu systems where libxcb-xinerama.so.0 isn't installed.

Based on this documentation https://doc.qt.io/qt-5/linux-deployment.html there should be a configure switch to disable xinerama at all.

But, when I tried ./configure -no-xinerama I'm getting following error:

./configure -no-xinerama
+ cd qtbase
+ qt-everywhere-src-5.15.1/qtbase/configure -top-level -no-xinerama
Creating qmake...
.Done.
ERROR: Unknown command line option '-no-xinerama'.

Is this switch still available?

I also tried ./configure -list-features but there is no mention about xinerama. I see Xinerama mentioned only in ./configure -list-libraries:
xcb_xinerama
xcb_xinput
xcb_xkb
xcb_xlib
xkbcommon
xkbcommon_x11

But I didn't find any -no-feature equivalent for -no-library.

PS: Also -no-xrandr doesn't work as mentioned in the documentation
