I recommend / tested Jani's solution.
BTW, my 'convert' (ImageMagick) is very slow and CPU consuming:
GENPDF Documentation/media/uapi/v4l/selection.svg
takes approximately 20% - 30% of the **complete** build time
of the 'pdfdocs' target. Its only with 'selection.svg'. The
other conversions are fast.
Is this only to me?
Here is what I have installed ...
$ convert -version
