Yes, this is what I meant. Not an absolute path, of course.

Right. Or maybe in all cases, even in different prefixes?
E.g. SYSCONFDIR set to etc/kde5 gives /etc/kde5 and $HOME/myprefix/etc/kde5.

How is this different from today's world, with Qt in /opt/qt5/lib, soprano in 
/opt/soprano/lib and qjson-git in $HOME/qjson/lib ?
We are not inventing anything new here.

Neither, I would say. You install into $CMAKE_INSTALL_PREFIX/$LIB_INSTALL_DIR
where LIB_INSTALL_DIR is set by cmake (e.g. GNUInstallDirs.cmake if that does 
the job).

If e.g. openSUSE wants to install everything into lib64, then it has to 
configure cmake to do so. I.e. cmake should install a file that contains the 
relative paths to use (that's what I meant by a ConfigFoo-like file, but ok, 
it's about relative paths only).
