Open Source Computer Vision Library
opencv.org
Use `link_libraries` instead of `add_defintions` to link against Qt 6.9 and newer to avoid un-expanded generator expressions from Qt cmake files being appended to linker flags when building the HighGUI module. The actual bug is likely in how Qt cmake files end up with these un-expanded generator expressions in the first place — see discussion in https://bugreports.qt.io/browse/QTBUG-134774 — but the recommended way to link against the library is to use `link_libraries` anyway, so this fix should do the trick. Fixes issue #27223. |
