Re: error when linking display_qt

This problem has been resolved; becoming apparent after including -DCMAKE_FIND_DEBUG_MODE=ON to the cmake invocation. The QWT library was explicitly set to
(the FILE PATH) -DQWT_LIBRARIES=/usr/lib64/ as opposed to (THE LIBRARY) -DQWT_LIBRARIES=/usr/lib64/libqwt-qt6.so
The library location: /usr/lib64/libqwt-qt5.so -> libqwt-qt5.so.6.2.0
I now have only one failed test to debug; moving on.
