I had a similar failure.

There are several approaches here and I've patches for two of them if
needed (I've attached them):
(1) backport some upstream patches:
    - There are 2 catch2 updates, they can be squashed into 1 patch
    - We also need a patch for fixing unused variables.
(2) Update cpp-mustache: There is an upstream commit
    
(https://github.com/kainjow/Mustache/commit/4ed8c0b5a2a43d59394bd6900dc04e738dbf8c02)
    that change some version string. I've asked upstream if that was
    the 5.0.0 release but so far I got no answer.
    https://github.com/kainjow/Mustache/issues/65

(1) is 0001-gnu-cpp-mustache-fix-build-with-newer-glibc.patch
(2) is 0001-bug-reported-upstream-for-release-info-gnu-cpp-musta.patch

I didn't share the patches yet because I was waiting on upstream to
clarify the situation with the lack of 5.0.0 tag.
