Module installation with Qt5.1 does not generated header files

[yazwas]

Good day
I wrote a module using Qt5.0 and it used to install the header files correctly with sudo make install

Now using the same code with Qt5.1 and compile it, only generate MyContactsDepends under /include folder

the file contains the following

@/* This file was generated by qmake with the info from <root>/src/contacts/mycontacts/mycontacts.pro. */
#include <QtCore/QtCore>
@

With previous versions of Qt, it also created MyContacts files and all .h files

This is the .pro file for the module

@TARGET = MyContacts
QT = core-private
CONFIG += qt debug

load(qt_module)

include(details/details.pri)

PUBLIC_HEADERS +=
mycontact.h
mycontactabstractrequest.h
mycontactaction.h
.....

PRIVATE_HEADERS +=
kmcontact_p.h
mycontactabstractrequest_p.h
.....@

Can anyone suggest a way around this or what I'm doing wrong?

Thank you!
