The generated dynamic library cannot be used in my project

[wslyw]

Hello, my default development environment is Qt 5.15.2 with MSVC 2019 64-bit, and I have built both the .lib and .dll files using qmake. However, I am encountering compilation errors when trying to use them in my project. I have also attempted to modify the .pro file, but it has not resolved the issue.
Here is the .pro file after my modifications.

TEMPLATE = lib

CONFIG += c++17

DEFINES += ADS_NAMESPACE_ENABLED ADS_EXPORT
QT += core

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

INCLUDEPATH += $$PWD/include

RESOURCES += \
	res/ads.qrc

!isEmpty(target.path): INSTALLS += target
include(AdvancedDockingSystem.pri)

And here is the part in my project related to importing the library and header files.

win32: LIBS += -L$$PWD/lib/ -lAdvancedDockingSystem
INCLUDEPATH += $$PWD/include
DEPENDPATH += $$PWD/include

The error message is:
