How Do I Integrate External Libraries, Like Psapi.lib, into My Qt Creator Projects?

Integrating External Libraries into Qt Creator Projects

Adding external libraries to projects developed using Qt Creator enhances their functionality. A scenario encountered by developers is incorporating the win32 function EnumProcesses(), which necessitates the addition of Psapi.lib to the project.

Solution

Qt Creator provides a systematic approach for integrating external libraries:

LIBS  = -L/path/to -lpsapi

This method ensures compatibility across all platforms supported by Qt. It separates the directory from the library name, excluding the extension and any 'lib' prefix.

For libraries stored within the project directory, the following syntax references the variable $$_PRO_FILE_PWD_:

LIBS  = -L"$$_PRO_FILE_PWD_/3rdparty/libs/" -lpsapi

By following these guidelines, developers can successfully incorporate external libraries into their Qt Creator projects, enabling the use of additional functions and extending the capabilities of their applications.
