QtWebkit build and installation: Unknown module(s) in QT: webkit

[T4QT]

HI

I am able to compile and build the Qt with, webkit . But when I checked the qt_source/qtbase/lib there were no libQt5Webkit.so library files. All the libraries related to Webkit were found qt_source/qtwebkit/lib. Now if I do the make install all the libraries were copied over the qt_source/install folder.

Now this creates the problem for me; when I am trying to build the project and make file with the use of
QT += webkit; I got the project error: Unknown module(s) in QT: webkit

I have included ICU libraries during the configuration time; and that's why webkit directory has the lib4Qtwebkit.so files.

any idea on this.

when I ran qmake -d; it gave this message:

qt-src/qtbase/mkspecs/features/qt_functions.prf: calling built-in error (Unknown module in QT: webkitwidgets)
