libksanecore-dev package, which this package depends on, was not properly installed, resulting in the loss of some files. By visiting https://packages.debian.org/sid/amd64/libksanecore-dev/filelist, it can be confirmed that this package does not include the /usr/lib/riscv64-linux-gnu/cmake/KSaneCore/KSaneCoreConfig.cmake file required by libkf5sane. Could the dependency on KSaneCore in the CMakeLists.txt file be updated to KSaneCore6 instead?
