Troubleshooting

#Stale debug CMake exports

Old debug installations can leave KF6*Targets-debug.cmake fragments that refer to libraries which no longer exist, and CMake then fails to configure later packages. Preview them with:

./cleanup-stale-cmake-debug

Remove the confirmed stale fragments with --apply. Use --prefix PATH (repeatable) to inspect an installation outside /usr, such as state/install-stage/usr. The command is never run automatically by build-all.
