Eike Ziller 5e1f40a3af CMake: Don't add standard Linux paths to LD_LIBRARY_PATH ...

If a project specifically links to a library in a standard path (like
/usr/lib/...), we do not need to add that path to LD_LIBRARY_PATH.
Actually adding it can be harmful if the build needs to link against
some other library in a different version than is available in the system
path.

Common case is linking the application against a Qt version from the
online installer. If /usr/lib/... ends up in the LD_LIBRARY_PATH before
the path to the Qt from the online installer, the system Qt is picked up
at runtime instead of the Qt from the online installer.
