Hello hwloc doesn't have any cuda specific configure variables. We just use standard variables like LIBS and CPPFLAGS. I guess OMPI could propagate --with-cuda directories to hwloc by setting LIBS and CPPFLAGS before running hwloc m4 functions, but I don't think OMPI actually cares about hwloc

[Moving To Devel] I tried to look at the configure to understand why the hwloc part failed at getting the CUDA path. I guess the --with-cuda information is not propagated to the hwloc part of the configure. If an m4 expert has an idea of how to do this the The Right Way, that would help.
