It's gonna be fairly painful, since the backend is a C program not a C++
program, and therefore it does not provide any of the infrastructure
that C++ code is likely to expect --- no exception stack, no global
constructors/destructors, no C++ library, etc.  I am not sure how much
of this is practical to load after-the-fact in a dynamic library.

My inclination if you really need to use ImageMagick would be to shell
out to the IM executable via system() (or better popen(), if you have a
modern popen that supports 'r+' access).
