Oh, I didn't know Mint provided such a poor Qt support. Then it won't be 
that simple, because Kdenlive relies on the KDE frameworks libraries, 
which have to be compiled with the same Qt version as Kdenlive. You will 
need to remove all system KDE libraries and manually rebuild. Compile 
the following KDE frameworks in that exact order :
||

|extra-cmake-modules karchive kconfig kwidgetsaddons kcompletion 
kcoreaddons polkit-qt-1 kauth kcodecs kdoctools kguiaddons ki18n 
kconfigwidgets kwindowsystem kcrash kdbusaddons kitemviews kiconthemes 
kjobwidgets kservice solid sonnet ktextwidgets attica kglobalaccel 
kxmlgui kbookmarks kio knotifications|
||knotifyconfig knewstuff kpackage kdeclarative||
||breeze-icons kdecoration breeze| These libraries are all available 
through git with the following command :|
||

git clone git://anongit.kde.org/$FRAMEWORK (where $FRAMEWORK is the name of each framework)

|Then for each framework you need to create a build dir, and compile 
using something like: cmake .. -DCMAKE_INSTALL_PREFIX=/usr 
-DKDE_INSTALL_USE_QT_SYS_PATHS:BOOL=ON If you are interested, I have a 
script to build the AppImage version that might help you (but will need 
several changes to work directly) at:

Check if you have the file mlt-framework.pc, you can see its content with:
cat mlt-framework.pc

Check the version there. You probably have a .pc file pointing to 6.5.0 
version in /usr/lib/pkgconfig. Easiest is probably to delete these 2 
files and reinstall MLT.

Kdenlive tries to locate MLT using pkg-config. You can verify with the 
following command:

pkg-config --libs mlt-framework

It should output something like:
-L/usr/local/lib -lmlt

And /usr/local/lib should contain your 6.6.0 libraries
