On systems with a system-local hwloc installation, the cmake charm++ build fails, as outlined in #3843 . I've never written autoconf before so I'm looking for feedback on this fix. Might be too hacky...
The issue, as suggested by compiler warnings, is that the HWLOC_SYM_* variables are defined twice, due to inadequate #ifdef wrapping. Specifically, two different header #ifdefs that don't align (HWLOC_CONF_H and HWLOC_CONFIGURE_H). At first I thought that header naming might be the issue, but the distinction is necessary.
Note that this PR does fix the mentioned issue.
