Deploying sqlite app

[codeman]

Hello friends,

today I try to start an App on a machine without any qtstuff. I get some error like this:

Unable to establish a database connection.
This Example needs SQLite  support. Please read the Qt SQL driver documentation for information how to build it.

To copy to clipboard, switch view to plain text mode 

So I have a tree like this:

deploy
|----->bin
|-------------->app.exe
|-------------->QtCore4.dll
|-------------->QtGui4.dll
|-------------->QtNetwork4.dll
|-------------->QtSql4.dll
|-------------->QtXml4.dll
|-------------->mingwm10.dll
|----->images
|----->sqldrivers
|------------>qsqlite4.dll
|------------>sqlite3.dll
in my app I add the line :

qApp->addLibraryPath("..\\sqldrivers");

qApp->addLibraryPath("..\\sqldrivers");

To copy to clipboard, switch view to plain text mode 

So what goes wrong here???

I install the default sdk with the installer 2009.04....
