Hi,

Not certain why that dependency problem occurs - will have to look
into it a bit further but it seems to be rpm issue (somehow it gets
the file dependencies wrong with symlinks to symlinks).

As a workaround you could disable auto requirements generation by setting:
set(CPACK_RPM_PACKAGE_AUTOREQ "NO")
