add "Compile and link statically to a bundled C++ library" example

[budziq]

Use cc crate to compile and link statically to a bundled C++ library inside of a build.rs file.

Please note that it will be important to mention that this is a build time crate.
Most likely we will dedicate a separate (last) chapter like "build_time.md"

cc #236

That link is broken for me - did the crate change it's name to cc? It seems to refer to itself both as cc and cc-rs. I'm assuming this is the crate you are referring to

[budziq]

@j-haj darn they renamed again. I've updated te link. Thanks!

[thibaultbarbie]

I would like to take it if it is ok ?

[hackertron]

Is this issue still open for contributor ?

[budziq]

@hackertron unfortunately it already has a PR awaiting review (please note the "wip / claimed" label) but you ar welcome to chose any nonclaimed example or propose a new one!

[budziq]
