Look for globally installed libraries

[montyly]

In some cases, truffle can compile codebase with libraries without the need from a local npm install. I am not sure when this happens, but my best guess is that the libraries are installed globally.

It happened most of the time with the OZ libraries.

If the libraries are not present in node_modules, we should look in the globally installed libraries

What about also looking for locally installed libraries when they are imported? Looks like it's unsupported (at least for solc platform)

Hi @yxliang01,

Do you have more context regarding "locally installed" libraries accessible by solc? Is it for the ones used through the remapping, or is it something else?
