Subject: Re: [hwloc-users] "-lnuma" missing from pkg-config information?

What's your compile line and how do you use package config?
Are you building with --static without passing --static to pkg-config?
@HWLOC_LIBS@ should only be needed for static linking so putting it in
Libs.private should be fine (it's returned by "pkg-config --libs
--static hwloc").
