I think CMake is putting it in the wrong place for you. Needs to be done via a patch.

You was right!
I found a temporary workaround.

/etc/portage/env/latomic.conf
LDFLAGS='-latomic ${LDFLAGS}'

/etc/portage/package.env/plasma
kde-frameworks/syntax-highlighting latomic.conf

Now sudo emerge -av syntax-highlighting works perfectly.
