No, the test project (like the plugin itself) are Release. I am attaching the .pro file of the test:

QT       += core gui
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
CONFIG += c++17
 
# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
 
SOURCES += \
    main.cpp \
    widget.cpp
 
HEADERS += \
    widget.h \
    analogclock.h
 
FORMS += \
    widget.ui

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++17

# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
    main.cpp \
    widget.cpp

HEADERS += \
    widget.h \
    analogclock.h

FORMS += \
    widget.ui

If it can be useful, I also put the .pro of the plugin:

QT          += widgets uiplugin
 
QTDIR_build {
# This is only for the Qt build. Do not use externally. We mean it.
PLUGIN_TYPE = designer
PLUGIN_CLASS_NAME = AnalogClockPlugin
load(qt_plugin)
CONFIG += install_ok
} else {
# Public example:
 
CONFIG      += plugin
TEMPLATE    = lib
 
TARGET = $$qtLibraryTarget($$TARGET)
 
target.path = $$[QT_INSTALL_PLUGINS]/designer
INSTALLS += target
}
 
HEADERS     = analogclock.h \
              customwidgetplugin.h
 
SOURCES     = analogclock.cpp \
              customwidgetplugin.cpp

QT          += widgets uiplugin

QTDIR_build {
# This is only for the Qt build. Do not use externally. We mean it.
PLUGIN_TYPE = designer
PLUGIN_CLASS_NAME = AnalogClockPlugin
load(qt_plugin)
CONFIG += install_ok
} else {
# Public example:

CONFIG      += plugin
TEMPLATE    = lib

TARGET = $$qtLibraryTarget($$TARGET)

target.path = $$[QT_INSTALL_PLUGINS]/designer
INSTALLS += target
}

HEADERS     = analogclock.h \
              customwidgetplugin.h

SOURCES     = analogclock.cpp \
              customwidgetplugin.cpp

Where do I find the reference of dllimport in Qt code ? Please note that here I'm doing everything only in Qt environment, including IDE, for the moment I don't use Visual Studio C++ (here the same plugin project works fine, including the test program).
I want to be able to make everything work in Qt environment, so I can finally verify the old QLed problem that you will remember well :-))
