CLUES:
It seems like this is a known bug for Redhat systems [1][2] since 2017.
This gives at least two puzzles:

(1) Why hasn't the fix been upstreamed to xz? (hypothesis:
because this is a one-person email-or-irc-bug-report maintained program; see
MAINTAINABILITY below)

(2) Why does maneage compiling _cmake_ have a problem with the _lzma_
library api on a redhat machine but not on another machine, since
high-level software should be isolated from OS-dependent library
apis like this?

On a machine on which a merge with 27ff6f7 compiled successfully,

$ ldd .local/bin/cmake |grep lzma
liblzma.so.5 => /BUILD/software/installed/lib/liblzma.so.5
(0x00XXXXXXXXXXXXXX)


It is also possible that the patch proposed in [2] itself creates a 
bug on redhat systems [3], as of a report in 2022, per Easybuild [4]
users/developers.

[3] https://github.com/easybuilders/easybuild-easyconfigs/issues/14991
[4] https://github.com/easybuilders/easybuild-easyconfigs

The relation between xz and lzma is not clear to me - understanding this may
help for finding a portable, safe solution. 


MAINTAINABILITY of xz:

The [https://git.tukaani.org/?p=xz.git;a=blob_plain;f=README;hb=HEAD
README] file of _xz_ says "Report your bug via email or IRC (see
Contact information below)." This means that if the main developer
is busy or ill, the community cannot fix the bugs without creating
its own fork, e.g. on a git repository.
