If you use Fedora cross-compile like I do, here's an example with fedora
specifics in it (debian vs fedora don't agree on lib path, but the rest shall be
similar regarding using generic toolchain that does not know were is your
rootfs).

If you want to know more about my NFS setup, let me know, dnf have been very
nice and simple tool to manage NFS rootfs for multiple boards for me, while
doing the cross-compilation on a fast machine.

p.s. Always make sure both host and rootfs Fedora are on sync, applies to Debian
and Ubuntu also (use dockers/podman image on host if you can't match), and be
aware that sometimes they may get out of sync for few days due to build issues
on Fedora side. What breaks most often is QT5 support, I have added -
Dqt5=disabled, useful if you need that.
