Build mysql driver for Qt5..5.1 for windows gives error:mysql.h: no such file or dir

[GoranSimunic]

Dear all,
i got this mistake when compiling driver by seppemagiels instructions on windows.

what is my mistake?
this is my Qt and mysql dir:

C:\Qt5\5.5\Src\qtbase\src\plugins\sqldrivers\mysql
C:\MySQL\MySQLServer5.5
both are 32 bit installations on 64bit machine

I have no spaces in dir name
I ran prompt as administrator...


Setting up environment for Qt usage...
