Subject: CMakeLists: use absolute libdir in rpath handling
Patch-mainline: no
References: rpath fix

The original rpath handling in the wiki[1] uses
"${CMAKE_INSTALL_PREFIX}/lib". But here, "${CMAKE_INSTALL_LIBDIR}" is
used.  While the former is absolute, the latter needs not. That causes
troubles as rpath can be set to something like "lib64" only. That is
bogus.

So fix this by using absolute "${CMAKE_INSTALL_FULL_LIBDIR}" from
GNUInstallDirs and handles the paths correctly.
