How to add a custom dynamic library in Qt?

To add a custom dynamic library to a Qt project, you can follow these steps:

1. Copy the custom dynamic library file (usually a .dll file) to the project directory of the Qt project, for example placing it in a subfolder called “libs” in the project.
2. Add the following content to the .pro file in the Qt project:

LIBS += -Llibs -lYourLibraryName

YourLibraryName is the name of the custom dynamic library, excluding the file extension.

1. Include the header file of a custom dynamic library in the source code files of a Qt project, and make the respective function calls and operations.
2. Recompile and rebuild the project to ensure that the custom dynamic library is correctly linked and utilized.

Please note:

1. The header file for custom dynamic libraries should be provided along with the library file in order to declare functions and define types in the project.
2. If a custom dynamic library depends on other third-party libraries, you need to add the appropriate linking commands in the .pro file, for example:

LIBS += -lThirdPartyLibraryName

1. If the custom dynamic library is not located in the project directory of the Qt project, you can specify the correct library file path by adjusting the parameters of the -L option.
