Build MySQL plugin using QtCreator

[gtpt]

Hello,

I want to build the MySQL plugin using QtCreator.
I have the 5.0.1 version and MySQL Server 5.5 (32bit) on Windows7.
I edited the mysql.pro file, located in C:\Qt\Qt5.1.0\5.1.0\Src\qtbase\src\plugins\sqldriv ers\mysql, and added:
@ INCLUDEPATH += C:/PROGRA~2/MySQL/MYSQLS~1.5/include
QMAKE_LIBDIR += C:/PROGRA~2/MySQL/MYSQLS~1.5/lib
LIBS += -lmysql@

After building the realease folder is empty!
What is missing in the QtCreator configurtion?
