macdeployqt on homebrew installed frameworks

I'm trying to deploy an application using macdeployqt. All Qt frameworks get copied correctly into the application bundle. The problem I encounter is that macdeployqt does not have write permissions on the copied frameworks which originally reside in /usr/local/lib. This is because I have installed qt using homebrew which seems to make install everything read only. My question is whether there is a better way to fix this issue then manually changing all permissions of the qt libraries inside /usr/local/lib so that I can use macdeployqt from within a qt .pro project. (I don't want to use macdeployqt manually with sudo or such)

The reason why I'm asking is because I am using many third party libraries in the project (they get copied ok etc.) which I need to update often through homebrew and thus have to redo the permission changing on them.

Thanks in advance!
