We default to configuring examples as separate ExternalProjects when
using a developer / non-prefix Qt build.
This ensures we test that the examples configure successfully without
the pollution of the main Qt build (e.g. already found packages).
One down-side of this is that a developer's IDE doesn't see these
example targets, unless each project is loaded into the IDE
separately. This is cumbersome to do when refactoring or renaming
code across multiple example projects.
Allow configuring the example projects as part of the main Qt build
by setting QT_BUILD_EXAMPLES_AS_EXTERNAL to FALSE when configuring Qt.
Save the value of the variable in QtBuildInternalsExtra.cmake.in
so it's propagated to leaf repositories as well.
