qt5base-lts/tests/auto/widgets/styles/qstyle/tst_qstyle.cpp
Jens Bache-Wiig 570ae40f57 Remove CDE and Motif styles from qtbase 
It is time to clean up some of our legacy code. These styles have
not been actively maintained for a long time and I think it is safe
to say that they should no longer belong as part of the default
distribution of Qt. We dont support any platforms based on CDE with
our source packages.

Note that even if we are removing these styles from the default
distribution of Qt, applications that depend on them
will still be able to bundle the existing (and unmodified) styles
along with their own source code as we are not breaking compatibility.
