The problem I'm addressing with my patch is configure time vs. install
time path resolution -- if you explicitly use the variable there, you
generate an absolute path at configure time, and it remains absolute
during installation, while a relative path has a variable reference
implicitly prepended to it which is resolved at install time.

So using CMAKE_INSTALL_DATADIR wouldn't work, what is needed is some way
to say "relative to whatever the variable is set to during installation".

The traditional way to install with stow is to configure for a prefix of
/usr/local, then override that as /usr/local/DIR/kicad for installation
and symlink the files into the /usr/local tree -- that way, if you have
compiled-in paths, they will use the /usr/local prefix, so the software
will only be a tiny bit confused if it expects its data files not to be
symlinks).

This is very close to what we do with DESTDIR (which is what most
distros use), but works without an extra renaming step.
