The order is wrong, as you can see. libQt5Sql.a appears before the plugins.

Invert the order and make the plugins appear before the library in this link 

It's interesting that the order is mostly correct. It seems that CMake is 
applying dependency sorting correctly. If that is the case, then either it's a 
CMake bug or there's some information missing in the qmake-generated CMake 
files. Reporting a bug here is unlikely to get you enough attention, so you 
may want to get your hands dirty and debug yourself.

It's also interesting that QtCore and QtNetwork are listed three times.
