Synergize Libdl.find_library and include_dependency

[Jay Weisskopf]

I maintain a package that wraps a dynamic library. To better support pre-compilation, the first thing I tried was:

const lib = Libdl.find_library(...)

include_dependency(lib)

Unfortunately, my intuition was wrong because find_library's return value does not include the library's file extension. Is there a simple way to handle this that I'm missing? I could append the file extension, but it varies depending on platform, and I'd rather not try to (poorly) create the logic to figure it out.

Libdl.dlext ?

[Jay Weisskopf]

Ah, yeah, that should do the trick. I wasn't aware of it since it's not in the docs. Guess I should have tab-completed "Libdl." in my REPL :-)

Doc improvements are always welcome, and best made by the people who would
have benefited from them. :-)
