LINK_PRIVATE is in cmake/shared.cmake in target_link_private_libraries,
which I added to tighten up library requirements.  It's just a flag, not
a library itself.  This flag should be supported by CMake 2.8.7 and up,
which the function I wrote tries to account for.  I've successfully
build with RHEL6 (cmake 2.8.4) and RHEL7 (cmake 2.8.11), so I hope that
compatibility logic is ok.

What version of CMake are you using?  I never tried 2.8.7 exactly -- I
just set the version there because that's the first release I found in
which documentation said LINK_PRIVATE should work.

Is there anything significant in this patch?

The libraries should be paths to libdwarf.so and libelf.so, not just the
directories containing them.  Which probably explains this:

etc. etc.
