We tried it in a 2.6.x, which is more recent than that, and it didn't work. 
(We ended up with things like /usr/lib or /usr/lib64 being set as an rpath, 
which is against Fedora guidelines.)

That's because we had the issue with 2.6.

That information is outdated. 2.4 relinked the binaries, 2.6 uses some 
direct ELF editing hack to edit the rpath out instead (it's faster).

That's interesting. I thought these come from CMake itself.
