[PATCH 02/36] configure: optional library sfsexp

Subject: [PATCH 02/36] configure: optional library sfsexp

Date: Tue, 24 Aug 2021 08:17:11 -0700

From: David Bremner

The configure part is essentially the same as the other checks using
pkg-config. Since the optional inclusion of this feature changes what
options are available to the user, include it in the "built_with"
pseudo-configuration keys.
