A configure script would simply compile a small program and link with that lib
and use the specific function and see if it works. That then also works for
static libraries which your version doesn't. dlopen() isn't even as widely
available as libraries are.

https://www.gnu.org/software/autoconf/manual/autoconf.html or plaing google
for it. autoconf has the benefit that it is old and is widely used so there's
almost always someone else out there who already solved any problem you can
think of.
