| <p>Searches for all installed versions of Qt.</p> |
| <p>This should only be used if your project can work with multiple |
| versions of Qt. If not, you should just directly use FindQt4 or |
| FindQt3. If multiple versions of Qt are found on the machine, then |
| The user must set the option DESIRED_QT_VERSION to the version they |
| want to use. If only one version of qt is found on the machine, then |
| the DESIRED_QT_VERSION is set to that version and the matching FindQt3 |
| or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION, |
| then the FindQt3 or FindQt4 module is included.</p> |
| <p>This module can only detect and switch between Qt versions 3 and 4. It |
| cannot handle Qt5 or any later versions.</p> |
