This looks very similar to an issue seen while trying to package
fuzzylite, and debian had a patch for it:

  https://salsa.debian.org/debian/fuzzylite/-/blob/debian/sid/debian/patches/fix-tests2.patch

It basically switches to using "catch2" headers instead of "catch"
headers...

A similar patch might work for cpp-mustache?
