+   For Unix-based systems, we try to use system libraries whenever available.
+   This means optional components will only build if the relevant system headers
+   are available. The best way to obtain the appropriate headers will vary by
+   distribution, but the appropriate commands for some popular distributions
+   are below.

+   One solution is to install these libraries from a third-party package
+   manager, like Homebrew_ or MacPorts_, and then add the appropriate paths
+   for the header and library files to your ``configure`` command.
