From c0659c8e2bb520abb940dd2303969fc468101a16 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Bug 791422 - gnucash 2.7 no longer opens sqlite3...

as it doesn't load proper backend.
The cause was that the libdbi-driver path in CMakeLists.txt was wrong
and GNC_DBD_DIR was being set unconditionally in etc/gnucash/environment
with an invalid path.
