Where's "libnextcloudsync.so.0"? In "/usr/local/lib"? AFAIK, nothing
installs anything into "/usr/local/lib/x86_64-linux-gnu" when you run
"make; make install" [1].

Is "/usr/local/lib" in the "ld.so.conf" path? Did you run "ldconfig"
after your installation?

On my laptop:

# dpkg -S /etc/ld.so.conf.d/*
libfakeroot:amd64: /etc/ld.so.conf.d/fakeroot-x86_64-linux-gnu.conf
libc-bin: /etc/ld.so.conf.d/libc.conf
libc6:amd64: /etc/ld.so.conf.d/x86_64-linux-gnu.conf

# grep local /etc/ld.so.conf.d/*
/etc/ld.so.conf.d/libc.conf:/usr/local/lib
/etc/ld.so.conf.d/x86_64-linux-gnu.conf:/usr/local/lib/x86_64-linux-gnu
