Description
I am cross-compiling Qt 6.2.0 for an Embedded Linux arm device (OpenGL ES 2) running Debian 11.
QtWebEngine built successfully. But i received an undefined reference to "XkbGetState" linker error for QtWebEngineCore.so:

After checking the source i saw that the section is guarded with a xkbcommon build flag. So i got it fixed by also linking libX11 in "qtwebengine/src/core/ozone/BUILD.gn" (see the attached diff/patch).
But i don't know if this is the correct way to solve this or if i missed something in the first place?
