Using use_local_qt_libs

Thu Jan 3 20:21:53 UTC 2013

For BogDan's step 3, you can find the "deploy local qt libs" option in the
"Run" settings for your project in the "Projects" tab of Qt Creator. After
you click on "Projects", you'll see the various targets for your builds,
and underneath the name of each target you'll see "Build" and "Run". Click
on "Run". That's where the settings are.
