Building cppyy and its dependencies from source for a custom CPU architecture

[vanotuvanov]

Hello!

I'm planning to build cppyy from source along with all its dependencies, as the target system has a non-standard CPU architecture.

Could you please advise:

1. What are the required dependencies for a complete build of cppyy?
2. Where can I find the source code for these dependencies (official repos or mirrors)?
3. Are there any special considerations when building for custom architectures?

Thanks in advance for your help!
