From 58d00bad1a2c4298bd58013e4808899feb657422 Mon Sep 17 00:00:00 2001 From: Guy Harris Date: Sun, 14 Feb 2016 17:00:38 -0800 Subject: Build the extcap programs in the extcap directory. That lets the version of Wireshark built with autotools find the extcap programs. Don't install the extcap programs under ${datadir} - that puts it under a share directory, and share directories are for platform-independent files, which executable images aren't (they're instruction-set dependent, hence platform-dependent).
