How to generate a DLL link library using QT?

Creating a DLL link library in Qt typically involves the following steps:

1. Add the following content to the .pro file to specify the generation of the DLL link library.

TEMPLATE = lib
CONFIG += dll
DEFINES += MYLIB_LIBRARY

1. Write your class or function and place them in a separate class library project.
2. Export classes or functions in project header files using the Q_DECL_EXPORT macro.

class Q_DECL_EXPORT MyLibrary {
    //类定义
};

1. To specify the generation of a DLL linkage library, add the following content in the .pro file:

INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD
win32 {
    LIBS += -L$$OUT_PWD/ -lMyLibrary
}

1. Compile the project to generate a DLL library file.
2. Import and use your classes or functions in other projects by using the generated DLL library file.

I hope these steps will be helpful for you!
