Files installed to /usr/etc rather than /etc
Files that should be installed to /etc are installed to /usr/etc.
From Steffen's email of December 4, 2020
On the way I discovered that there's /usr/etc/root which is a RedHatism (/etc/root would be correct)
Resolved using CMAKE_INSTALL_SYSCONFDIR=/etc/root (not /etc as one might guess - so "something" in the project sets the default to $PREFIX/etc/root)
