Skip path-specified optional dependencies if they don't exist #2663

Closed CyberShadow closed 1 year ago

CyberShadow commented 1 year ago

I think this is a useful and harmless alternative way to understand "optional" in this context.

The motivation is being able to do autoconf-like optional dependencies: D packages may install a Dub package file somewhere on the system, which we can pull in if it is present, but silently skip if it's absent.
