Problem in using Custom Widget

Hi All,

I have created a custom widget, e.i, a label with a clicked() signal. It is properly showing in Qt Designer and I was able to add it on my project UI. The problem is during the compilation of my project, the following error occurred:

Code:

release/employeeentry.o:employeeentry.cpp:(.text$_ZN16Ui_EmployeeEntry7setupUiEP7QDialog[Ui_EmployeeEntry::setupUi(QDialog*)]+0x3f1): undefined reference to `_imp___ZN7HSLabelC1EP7QWidget'

Below are the codes of my custom label plugin:

HSLabel.pro

Code:

CONFIG      += designer plugin
TARGET      = $$qtLibraryTarget($$TARGET)
TEMPLATE    = lib
QTDIR_build:DESTDIR     = $$QT_BUILD_TREE/plugins/designer
 
CONFIG += release
HEADERS += \
    hslabel.h \
    customwidgetplugin.h
 
SOURCES += \
    hslabel.cpp \
    customwidgetplugin.cpp
 
target.path = $$[QT_INSTALL_PLUGINS]/designer
sources.files = $$SOURCES $$HEADERS *.pro
