* Build examples in isolated sub-builds using ExternalProjectCraig Scott2021-05-261-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
