Qt v.4 vs Qt v.5

[Dmitrij Kryzhevich]

Are there any benefits of linking mathgl with Qt5 against Qt4?

Dear Dmitrij,

There are no differences in functionality of Qt4 and Qt5 versions. Except the fact what some distributives, like Ubuntu, provide Qt5 as default Qt development version.

Note, that Qt5 looks not so stable -- I found at least 2 bugs (or bug for QSlider and undocumented "feature" for QAction) while supporting Qt5, which I had to specially bypass. And I'm not sure that another bug(s) will not appear or present -- I test most of things but ...

Now there are three mgl-qt libraries:
libmgl-qt.so.7.2.0
libmgl-qt4.so.7.2.0
libmgl-qt5.so.7.2.0
Two first are the same. Does libmgl-qt exist for backward compatibility?

Yes. In fact, libmgl-qt should be link to *-qt4 or *-qt5. But now, I have to build it separately due to issues of cmake.
