 Open in Qt Creator and build your application. Run it from the command line and inspect it with `ldd` to make sure the correct libraries from the correct locations are getting loaded, as `linuxdeployqt` will use `ldd` internally to determine from where to copy libraries into the bundle.
 
+__Important:__ `linuxdeployqt` deploys the Qt instance that qmake on the $PATH points to, so make sure that it is the correct one. Verify that qmake finds the correct Qt instance like this before running the `linuxdeployqt` tool:
+
+```
+qmake -v
+
+QMake version 3.0
+Using Qt version 5.7.0 in /tmp/.mount_QtCreator-5.7.0-x86_64/5.7/gcc_64/lib
+```
+If this does not show the correct path to your Qt instance that you want to be bundled, then adjust your `$PATH` to find the correct `qmake`.
