Autogen: Don't change the order of HEADERS array in AutogenInfo.json
Qt6 reads our internal AutogenInfo.json
file. In !5624 (merged), the ordering of the HEADERS
array elements was changed and this broke their cmake_automoc_parser
. We don't need to change the order of the array elements, we can append to the existing ones instead. Do this to allow their cmake_automoc_parser
to continue to work.
Fixes: #21823 (closed)
Backport: release
