## Detailed Description

### Using the Module

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

#### Building with CMake

Use the `find_package()` command to locate the needed module components in the `Qt6` package:

     find_package(Qt6 REQUIRED COMPONENTS Multimedia)
     target_link_libraries(mytarget PRIVATE Qt6::Multimedia)
