Hello
Your configure line should do exactly what you want, and that's the
whole point of plugins:

If ldd shows libcudart and libnvidia-ml dependencies in libhwloc.so, you
may use "make V=1" to verify the link command-line that built these
libs, and then find the relevant link line/options in Makefile, and then
in Makefile.am
