This seems to suggest that something in the package is linked to all the
libraries, and I don't see how you could remove it.

If it was only using dlopen(), you probably had to add those depends by
hand, which seem to be error prone to get the right versions.

If it's using dlopen(), you probably want to depend on the -dev packages,
unless you want to hardcode the complete name of the library instead of
the soname.  It probably already breaks if they're not installed.
