Build qt3D with qt4 under Ubuntu 12.10

[wysota]

Did you read the bolded note in the manual? Are you building Qt3D against a Qt installation you have write permissions for?

Hi, thank you wysota:

I manually created needed directories. Also, I used
sudo qmake
sudo make


Now, I found a way out , but IMHO, to build current Qt3D is still annoying and problematic.
