Documentation on per-library info in package_info is missing

[sigiesec]

https://docs.conan.io/en/latest/reference/conanfile/methods.html#package-info does not explain how per-libary information is set.

There is some unconsolidated information on this in conan-io/conan#1323 but it is unclear what is actually implemented in conan

[sigiesec]

In particular, it should be documented how the dependencies of each library are specified.

There is also some brief example at the very end of https://docs.conan.io/en/latest/creating_packages/package_approaches.html#n-configs-1-package, but this is quite vague. Which CONAN_LIB targets result from the example?

Hi @sigiesec

I am trying to understand what you are requesting here and my guess is that the "extensible" property of self.cpp_info is not well documented. Basically what it is proposed here: conan-io/conan#1323 (comment)

I think we can improve the reference and maybe add a how to on including custom parameters or multiconfig things, but not sure yet.

Have I understood the issue well? Thanks
