If the project is still growing, having to take care of aligning, testing, and
supporting multiple distinct build systems is a real cost. If it's not going
to change much nor acquire many new users, indeed maybe you can just not have
to care.

Cmake approach for cross is to produce a 'toolchain file' which specifies a
handful of crossplatform cmake commands to specify how to build cross...
usually this is fixing the toolchain path, your cross-root path, and turning
off search in build host dirs. This toolchain file is invariant for whatever
you will build with it, invariant also by build platform, and replaces the
cross tuples needed by autotools. If you have a bunch of things to build
cross, it's more flexible, consistent and simple to give this toolchain file to
your build host cmake and have it just work on every project you want to build
the same, than figure out what different distributed configure scripts often
created by different autotools eras want (not all projects agree on override
host / build / target or some combination to trigger cross) or know about (eg,
risc-v).
Like cmake has ctest, he also comes with CPack. This can produce packages of
various types (tarball, deb, rpm etc) for distribution using installation info,
and versions etc from CMakeLists.txt.

... anyway, good luck whatever you choose to do about it.
