digiKam 3.3.0 install

digiKam 3.3.0 install

So let me start by saying I'm new to ubuntu and am yet to successfully
install anything from a tarball...
I'm trying to install the digiKam 3.3.0 software package and after finally
getting open CV 4.2.6 to install (which gave me a lot of problems when
initially trying to install this digiKam 3.3.0) I'm getting this message
after: sudo checkinstall --pkgname=digiKam3.2 --install=no make install
I get this message:
Scanning dependencies of target kface [ 3%] Building CXX object
extra/libkface/libkface/CMakeFiles/kface.dir/kface_automoc.cpp.o make[2]:
* No rule to make target /usr/lib/libopencv_calib3d.so', needed

Error 2
** Installation failed. Aborting package creation.
Restoring overwritten files from backup...OK
Cleaning up...OK
Bye.
Any ideas how I can fix this?
BTW I'm using this as a guide to install digiKam...
