I did already and it seems ok to me:

 ldd /usr/lib/libqt5scintilla2.so | grep -i qt
        libQt5PrintSupport.so.5 =>
/usr/lib/x86_64-linux-gnu/libQt5PrintSupport.so.5 (0x00007f20a24e9000)
        libQt5Widgets.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5
(0x00007f20a1cc0000)
        libQt5Gui.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5
(0x00007f20a1672000)
        libQt5Core.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
(0x00007f20a0fcc000)
ldd /usr/local/qwt-6.1.2/lib/libqwt.so | grep -i qt
        libQt5OpenGL.so.5 => /usr/lib/x86_64-linux-gnu/libQt5OpenGL.so.5
(0x00007f97ca6f1000)
        libQt5Svg.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Svg.so.5
(0x00007f97ca4a5000)
        libQt5PrintSupport.so.5 =>
/usr/lib/x86_64-linux-gnu/libQt5PrintSupport.so.5 (0x00007f97ca23f000)
        libQt5Widgets.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5
(0x00007f97c9a16000)
        libQt5Gui.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5
(0x00007f97c93c9000)
        libQt5Core.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
(0x00007f97c8d22000)

grep -i qt4 CMakeCache.txt
//If enabled will try to find Qt5 before looking for Qt4

I cleaned ccache, make clean and rebuilt but still:

ldd /apps-qt5/lib/libqgis_gui.so |grep Qt | grep -v Qt5
        libQtSvg.so.4 => /usr/lib/x86_64-linux-gnu/libQtSvg.so.4
(0x00007f75f5501000)
        libQtGui.so.4 => /usr/lib/x86_64-linux-gnu/libQtGui.so.4
(0x00007f75f484d000)
        libQtCore.so.4 => /usr/lib/x86_64-linux-gnu/libQtCore.so.4
(0x00007f75f4368000)
