rpmbuild error on RHEL 7.4

[rajachan]

I am trying to build cerebro RPMs on a vanilla RHEL 7.4 node for use with LMT. I am working with commit 34257dd on master. An rpmbuild using a configure-generated .spec file errors out after failing to find a service file:

RPM build errors:
    File not found: /root/rpmbuild/BUILDROOT/cerebro-1.18-1.x86_64/usr/lib/systemd/system/cerebrod.service
    Directory not found: /root/rpmbuild/BUILDROOT/cerebro-1.18-1.x86_64/var/run/cerebro

A manual ./configure; make; make install seems to work but fails to install the necessary service files. What am I missing?
