different style between 2 Qt version

[dridk2]

I found something strange....
I have 2 versions of Qt installed on my system. The Qt from ubuntu repository and the Qt from qt.io installer;
When I run a QTableWidget with both Qt version, the style change.

Left : Qt from ubuntu repository
Right : Qt from web installer

So, That's come probably from KDE style . But How can I apply this style with the Qt web version ?

copy ls /usr/lib/x86_64-linux-gnu/qt5/plugins/styles/ to your web Qt installer path : /Qt/5.7/gcc_64/plugins/

Ok, the web installer version doesn't find the breeze style ... How can I tell him to find the style ?
