Hello,
Personally I use the following setup successfully (customize INSTALL_PREFIX to your liking) (included in my .bashrc to avoid retyping it):
    INSTALL_PREFIX=$HOME/apps/kdenlive
    export LD_LIBRARY_PATH=$INSTALL_PREFIX/lib \
           XDG_DATA_DIRS=$INSTALL_PREFIX/share:$XDG_DATA_DIRS \
           PKG_CONFIG_PATH=$INSTALL_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH \
           PATH=$INSTALL_PREFIX/bin:$PATH

then

cd mlt
./configure --enable-gpl --enable-gpl3 --enable-debug --prefix=$INSTALL_PREFIX
make -j4 && make install
cd ../kdenlive/build
cmake .. -DCMAKE_INSTALL_PREFIX=$INSTALL_PREFIX -DCMAKE_BUILD_TYPE=Debug
make -j4 install

but for sure Qt5.5 is really old.
instructions to setup a chroot here : https://community.kde.org/Kdenlive/Development/KF5#Older_Linux_Distributions
(just updated it to point to 17.10 instead of old 15.04)

Good luck!
