Fix building examples when doing a Qt static build
The build failed due to two different reasons. We tried to assign properties on an aliased target, which does not work. Make sure to set properties on the original unaliased target. We tried to query for the value of the QT_DEFAULT_PLUGINS property when automatically linking to plugins, but the generator expression failed in the AND section, because querying for an unexisting value does not return an integer, and the AND expression expects an integer. The fix is to wrap the relevant expression in a BOOL generator expression. Change-Id: Ia065bc1de939cee49e5de0b2aef70e356cc5419a Reviewed-by: Simon Hausmann <> Reviewed-by: Qt CMake Build Bot
