Disable by default, to be used by distributions who care to try and prefer system-wide libraries when available. It makes sense for us to keep using vendored libs by default when possible to make it easier for users to compile, but we should provide appropriate tools for distro to figure out which dependencies they can share with the rest of the system.

|
# dependencies list.
