QT based application rejected by Gatekeeper due to RPATHs issue.

I am building my application on QT 5.15.2 and QTWebkit (5.212).

The application is lunching successfully. The notorization of the app is also successful as per the "spctl" output(Screenshot attached). but when the app is launched at other systems, it gives "developer cannot be verified" message.

As per the system logs, its because of "rpaths" of QT libraries:
File /Volumes/X.app/Contents/MacOS/../Frameworks/QtWebKitWidgets.framework/Versions/5/QtWebKitWidgets failed on rPathCmd /Users/qtwebkit/qtwebkit-opensource-src-5.212/release/lib/QtMultimediaWidgets.framework/Versions/5/QtMultimediaWidgets (rpath resolved to: (path not found), bundleURL: /Volumes/X.app)

This application is already notarised with at QT 5.14.2 and working fine at on other system. But after upgrading to QT 5.15.2, this issue is coming.
