the Genode build system does not run qmake, but includes the qmake project file as if it were a Makefile. This works well for simple
project files, but if the project file uses qmake-specific syntax and these parts are relevant, they must be replaced with something
that GNU make understands. In your case it would probably suffice to just delete the 'static {' line and the '}' line.

The 'QT' variable gets evaluated in [1] and there's no svg support right now. A port of the Qt5Svg library would include the
following new files:

- repos/libports/lib/import/import-qt5_svg.mk
- repos/libports/lib/mk/qt5_svg.mk
- repos/libports/lib/mk/qt5_svg_generated.inc

The 'QTPLUGIN' variable does not get evaluated in the 'target_final.inc' file right now. To do that, I think you would need to add
each part of the variable content to the LIBS variable (prefixed with 'qt5_'), resulting in 'LIBS += qt5_qtvirtualkeyboardplugin' in
your case, and then build the plugin as a shared library, similar to the 'qt5_qjpeg' library.

I've attached the generated include files and a patch with the script used to generate the files, in case you need to change the
configuration and regenerate them.

Regards,
Christian
