dyld: Library not loaded: /usr/local/Qt-5.2.0/lib/QtWidgets.framework/Versions/5/QtWidgets

[dlwhitehurst]

Application has run within QT Creator, however Dynamic Library path was determined automatically by QT Creator. The error occurs when executing the generated app outside of QT in OS-X 10.13

First ran otool -l to determine existing rpath. Then did this to post-build executable.
install_name_tool -rpath @executable_path/Frameworks /usr/local/lib cybill-core

Leaving open because I hope to find a way to fix pre-build (qt.pro file)
