COMP: Fix redistributable system libraries in packaging
Created by: vovythevov
When Slicer switched to using component for packaging (issue #2397), it broke the packaging since CMake macro InstallRequiredSytemLibraries does not support components (see http://www.cmake.org/Bug/view.php?id=15428).
Until the macro is fixed, we can install the system libs under the right component. More information in issue #3972
