asciidoctor-mathematical does not install on Big Sur

[elisa-riscv]

I am copying Terminal output from several lines before the warning messages begin.

After upgrading to Big Sur and upgrading the command line tools to the latest version, I checked all of the dependencies for asciidoctor-mathematical.

It appears that there is a dependency on glib-2.0 but why?

Update the VERSION argument value or use a ... suffix to tell CMake that the project does not need compatibility with older versions.
