Subject: [PATCH] CMake build: Don't re-link libraries unnecessarily

If a library changes its implementation only, don't relink all
libraries that depend on it. This is usually not necessary since the
API stayed the same.

Fixes: QTCREATORBUG-25962
Change-Id: I0221b09afd92463c3dad40bd0107ba0d5668ac79
