They're not missing; they're just harder to get at now, for some
reason.

I have successfully built SLURM 19.05.3 on CentOS 8.  I'm still
verifying that everything works correctly, but here's my spec file
diff so far (safe to apply upstream, if desired...won't break other
distros):

I build with Mezzanine, but the equivalent would roughly be this:

  rpmbuild -ts slurm-19.05.3-2.tar.bz2
  cat the_above_diff.patch | (cd ~/rpmbuild/SPECS ; patch -p0)
  rpmbuild --with x11 --with lua --with pmix ~/rpmbuild/SPECS/slurm.spec

In order for that to work, though, you need to configure your yum/dnf
setup, like so:

  dnf -y install dnf-utils
  dnf config-manager --set-enabled cr
  dnf config-manager --set-enabled PowerTools
  dnf -y install munge-devel lua-devel json-c-devel lz4-devel

Hope that helps!
Michael
