Rewrite build-dependencies.sh in python/cmake

[mrexodia]

It looks like build-dependencies.sh currently only works on Linux (on macos 12 I get errors related to https://github.com/lifting-bits/cxx-common/blob/master/build_dependencies.sh#L95).

Would be nice if this script was rewritten in python or cmake so Windows can also be supported.

Are the bash errors related to an old version of bash that comes pre-installed on macOS? (Check this issue #953)

Would be nice if this script was rewritten in python or cmake so Windows can also be supported.

Rewriting in Python3 (ideally version 3.7 minimum) would be nice. I'll consider it.

Yeah I guess that’s the problem. If you want I can send a PR with a fix, I just replaced-z with a different pattern.

perhaps changing from bash to “sh” would be better though (given zsh supports the script)

A PR would be great! Thank you!

Edit: PR was made as #985
