plugins - How can I make my Qt app see the "platforms" in a different place? -

i'm aware that, when installing qt application somewhere, need deploy plugin related system being used in folder platforms . traditionally folder supposed located in same place executable located. want change that: want put folder 1 level back, is, in place ../platforms . how can tell app in place shared library? reading threads on web came 2 possible solutions: 1 use qcoreapplication::addlibrarypath() , "general plugins" (those should placed inside plugins directory), not platform plugin afaik. such tried solution adding "../" in call qcoreapplication::addlibrarypath() and didn't work. (should have put "../platforms" instead?) other solution seems using qt.conf . problem don't know how edit file when comes adding path platform plugin: digia's manual file doesn't tell how specific configuration. set plugins in qt.conf point location of plugin sub-directories (ie .. in example), rather listing individual plugin sub-dir
