In CMake 2.8.3 and earlier, libs listed in the 2nd arg to fixup_bundle were
copied into the bundle. Half the people using it considered that behavior a
bug, half liked it just fine.

In 2.8.4, we "fixed" the bug (really, transferred it to the other half of
the people)...

In retrospect, I never should have allowed that change to go into CMake, but
there you have it: 2.8.3 and earlier copy the plugins, 2.8.4 and later do
not.

So: if you want a plugin inside your bundle, with CMake 2.8.4 and later, you
have to copy/install the plugin into the bundle yourself before calling
fixup_bundle.


Sorry for the persisting confusion,
David
