Project ERROR: Unknown module(s) in QT: quick

Hi all,

i have compiled Qt5.1.1 with linaro toolchain.i compiled all the components/modules of Qt present in Qt5.1.1 including QtQuick1.Now after i do a qmake on qtdeclarative/tools/qmlscene i get this error "Project ERROR: Unknown module(s) in QT: quick".
I am also not bale to Add Qt += quick in Qtcreator as its is giving error "Unknown module(s) in QT: quick" .

All this is done on Ubuntu 12.04 LTS and Qtcreator 2.8.1.
Does anybody have any idea what iam doing wrong??Thanks in advance.
