static declarative app built with cmake fail to run

Using static build qtbase and declarative, building examples or apps using cmake fail to run, because it cannot find the declarative import plugins.

This happens on desktop as well as webassembly, which both use static. I presume it also effects iOS, which is static builds as well.

Using qmake still produces working apps.

Running cmake does not generate cpp files containing Q_IMPORT_PLUGIN for the declarative import plugins like qmake will do.
