According to this Qt blog post:
The -deep option signs the app bundle recursively, including contained frameworks. While convenient to use, –deep is documented for “emergency repairs and temporary adjustments only“. As of Qt 5.4 macdeployqt has a -codesign option that recursively signs the app bundle without using –deep.

Assuming you have an appropriate certificate in your keychain and are using Qt 5.4.x, then you should be able to codesign with the -codesign option
Where MyCertificate is the name of the signing certificate in your keychain
