Fails to build with Qt 6.9
System Information
OpenCV version 4.11.0 GCC 14.2.1 Qt version 6.9.0
Platform: openSUSE Tumbleweed (Linux) Archs: x86_64, aarch64
Detailed description
OpenCV version 4.11.0 fails to build with Qt6 version 6.9. When using ninja as the builder, cmake fails at the configure stage with:
ninja: error: build.ninja:13215: bad $-escape (literal $ must be written as $$)
A full log file corresponding to this build is attached: _log.gz.
Alternatively, when using make, the configure succeeds, but the build fails down the line nonetheless:

Steps to reproduce
Try compiling on a system with Qt version 6.9+ with highgui module enabled. The command used to configure is as follows (this is from an attempt to build the module with Qt6 as part of openSUSE Tumbleweed's RPM packages):

Issue submission checklist
- [x] I report the issue, it's not a question
- [x] I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- [x] I updated to the latest OpenCV version and the issue is still there
- [ ] There is reproducer code and related data files (videos, images, onnx, etc)
This seems to make it work, but no idea if this is the fix:

We're seeing the same in Fedora. The patch from @badshah400 fixes the build for us too. Thanks a lot.
I confirm that @badshah400's patch solved the problem for me too. Can it be added to the master?
@badshah400 could you make a formal pull request for this project to merge your patch ? Thanks in advance.
