CMake: Support manual multiple projects within-a-repo SBOM generation
Certain repositories like qtwebengine contain multiple projects from the perspective of online installer packaging. In this case the QtWebEngine and QtPdf projects are expected to have separate SBOM documents. Introduce a new QT_SKIP_SBOM_AUTO_PROJECT variable that can be set before qt_build_repo to disable the auto-generation of an SBOM document for the current repo project. Introduce two new internal functions qt_internal_sbom_begin/end_qt_repo_project to allow to manually start and end the SBOM generation for a project within a repo. Because the intermediate file names that assemble the SBOM use the project name as a key, and the project name would be the same for qtwebengine, allow differentiating between the current project name and the real qt repo project name. The current project name is used for the file names, whereas the real qt repo project name is used to extract the dependencies on other repos, to ensure correct dependency build rules. As a drive-by, improve the document dir path search list when an SBOM document can't be found. Pick-to: 6.8 Task-number: QTBUG-128893 Task-number: QTBUG-122899 Change-Id: I61b68098242e7c49b98420265c29af78303c3233 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
