Is the CPP file that contains
Digikam::QmlShow::QmlShow(QList<Digikam::ImageInfo>) compiled during the
build process? If not, you've made a mistake in the cmake configuration.

If it is linked, is the declaration of
Digikam::QmlShow::QmlShow(QList<Digikam::ImageInfo>) identical with the
definition (i.e. are header file and cpp file in-sync)?
