If Qt DS 4.6 cmake exporter is ran on a project which uses older version of qmlproject, there is no indication that the exporting goes south and then project won't run OK on the compiled Qt project.

Minimum requirement: 

• Check that qdsVersion in qmlproject is older than 4.5 and if - display a warning in the output log and highlight it so user is aware of the upcoming error.

• There is also https://bugreports.qt.io/browse/QDS-13551 which has comments what to do. We should list these in the Wiki as general note and point user to the wiki by a link in the output log.
• Link to the wiki page is: https://wiki.qt.io/QtDesignStudio/CMakeExporter
•
