qsql_oci.h: Unable to locate header file qsqlcachedresult_p.h

When I try to register the QOCIDriver I get the following error:

"C1083: Cannot open include file: 'QtSql/private/qsqlcachedresult_p.h': No such file or directory"

Please find attached my source code of my small test project.

I have located the header file "qsqlcachedresult_p.h" at the following location:

"5.0.0-beta2\msvc2010\include\QtSql\5.0.0\QtSql\private"

But when I change the #include in qsql_oci.h to

#include <QtSql/5.0.0/QtSql/private/qsqlcachedresult_p.h>

I get the following linker errors:
