The addition of the mock delegates plugin in this change triggered failures when configuring a combined Qt WebEngine and Qt Pdf build with tests activated:
CMake Error: Files to be generated by multiple different commands: "/Users/michaelbruning/dev-with-6.9/qt_sbom/qtpdf/DocumentRef-qtbase.cmake"

(see attachments for output with and without tracing)

It seems as if the addition of the internal module somehow causes the file to be generated twice. This seems to happen from the call to qt_internal_sbom_end_qt_repo_project, which then ends up calling _qt_internal_sbom_end_project_generate, where the GENERATE call happens.

This can be reproduced with dev/6.11, 6.10 and 6.9.
