So we can see the exact moc invocations when debugging issues in the CI. For ExternalProject examples, it is conditional on whether Qt is configured with QT_INTERNAL_VERBOSE_EXAMPLES set to ON, otherwise calling the main ninja without -v will end up cluttering the output with AUTOGEN output.

# hierarchy, without polluting the example projects with dirty INSTALL_EXAMPLEDIR and
|
|
# INSTALL_EXAMPLESDIR usage.
|
|
# E.g. ensure qtbase/examples/widgets/widgets/wiggly is installed to
|
|
# $qt_example_install_prefix/examples/widgets/widgets/wiggly/wiggly.exe
|
|
# $qt_example_install_prefix defaults to ${CMAKE_INSTALL_PREFIX}/${INSTALL_EXAMPLEDIR}
|
|
# but can also be set to a custom location.

|
|
# - when using ExternalProject to build examples
|
|
# - when examples are built in-tree as part of Qt (no ExternalProject).
|
|

|
|
# work with a Qt repo and its examples using the same build dir.

# similar.
