* Build examples in isolated sub-builds using ExternalProjectCraig Scott2021-05-261-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

* Fix Standalone Example build when crosscompilingLeander Beernaert2019-06-061-36/+2
| | | | | | | | | | | | | | | | | Added qt_examples_begin() and qt_examples_end() macros to setup the example list so it can be re-used in other projects. When cross-compiling, we also need to set CMAKE_FIND_ROOT_PATH_MODE_PACKAGE to BOTH in order for find_package() to work correctly. Removed support for building the whole qtbase/examples folder as a standalone project. Building examples is only supported when building the whole of qtbase (qtbase + examples together) or each individual example is built separately against an installed Qt version.

* Allow to build examples as standalone projectKevin Funk2019-06-051-2/+65
| | | | | | | | | | | | | | | | Create CMake config files which can be used from the very same CMake project. These CMake config files simply do not create any targets, controlled via the QT_NO_CREATE_TARGETS. This patch also allows to build qtbase.git:examples as a standalone project, against an already-built Qt.
