That sounds like a useful approach.

I like to make sure that the user is always in control.

Different Linux/FOO distributions use different names for similar 
packages.  So there may be multiple possible names for something like 
libjpeg, and sometimes even with a version number as part of the name.

Even linking DLLs under Windows is a torture test since normally they 
need all symbols defined in order for the link to succeed.

I will investigate this topic.  I like to be able to specify the 
library allocator to use so that memory limits can be enforced.

I used to have a helpful icon for it.  But I do not see the icon any 
more. :-(

If you have control of the SVG sources then you are able to test and 
see how well things work.

GraphicsMagick can be extended via the delegates.mgk file so it is 
possible to use an external SVG renderer.

The issue with msl.c, svg.c, and url.c should be fixed now by latest 
updates.
