Build
$ ninja ninja: error: 'app_autogen/include_Debug/ui_regular.h', needed by 'app_autogen:Debug', missing and no known rule to make it
Discovered and refined to the above reproducer, while investigating a failure on Windows when trying to build examples as external projects.
https://testresults.qt.io/coin/integration/qt/qt5/tasks/web_qt_qt5_1667580188137
agent:2022/11/04 20:23:10 build.go:394: ninja: error: 'src/designer/src/designer/designer_autogen/include_Debug/ui_preferencesdialog.h', needed by 'src/designer/src/designer/designer_autogen:Debug', missing and no known rule to make it
The way it's triggered in qttools is due to all example external projects depending on all targets in $repo/src, qttools has the designer app which refers to ../../../shared/qttoolbardialog/qttoolbardialog.ui
preferencesdialog.ui
When examples are not built, the problem does not trigger because qt_internal_add_app does
set_property(TARGET "${name}" PROPERTY EXCLUDE_FROM_ALL "$<NOT:$<CONFIG:${QT_MULTI_CONFIG_FIRST_CONFIG}>>")
and the debug variant of the executable is not built.
But with examples building on, an add_dependencies call between an external project custom target and the designer app target forces a dependency on all variants of the app, including debug.
