Oracle database connection failure

[atiker]

hello,
I am quite new to Qt and I want to establish connection between Qt and Oracle. I researched various articles even the online Qt documentation. None of them helped and end up with failure to connect Oracle database. Is there anyone can explain step by step guide for dummies to connect with Oracle database? My environment is:
OS=windows 10
Qt=5.10
Database=Oracle 12
Here is the Error message in Mingw32 environment;
C:\Qt\5.10.0\mingw53_32>cd C:\Qt\5.10.0\Src\qtbase\src\plugins\sqldrivers\oci

Cannot read C:/Qt/5.10.0/Src/qtbase/src/plugins/sqldrivers/qtsqldrivers-config.pri: The system cannot find the file specified.
Project ERROR: Library 'oci' is not defined.

I believe that the error raised because MSVC libraries cannot be used within MINGW. There must be some other solution to build QOCI driver. Can anyone help?
Thanks in advance.
