OpenBSD has shm_open directly in libc, and we dont have librt, so build fails at some point when a test binary tries to link with SHM_LIBS.

I got the impression that the autotools build system might be on its way out. You might want to do the same fix in CMake land. (CC'ing mrobinson who will know.)
Comment on attachment 226221 [details] Patch It looks like the CMake port doesn't explicitly link against librt. It may have to once it is tested on more systems, but I don't think this fix needs to be extended to CMake yet.
