Installation is always relative to CMAKE_INSTALL_PREFIX. On Linux, this defaults to /usr/local. Using the variables from GNUInstallDirs module saves you lots of trouble like library locations on Debian or Rehat.
It's actually pretty simple and only very special cases differ from this.

The problem is the drive letter of the absolute path that can hardly be concatenated with a staging folder that you can define with DESTDIR like
  make install DESTDIR=mystagedir

and the files go to their relative locations in
<DESTDIR>/<CMAKE_INSTALL_PREFIX>/

You gain a lot more flexibility by adopting this than hard encoding path in the install() commands.
