Sorry, I was thinking of the wrong part of module loading. The messages you got
are from before the module is passed to dlopen and come from
gnc_module_load_common
(https://github.com/Gnucash/gnucash/blob/maint/libgnucash/gnc-module/gnc-module.c#L447).
That function does search, using the path set in $GNC_MODULE_PATH, and cmake
writes that into <prefix>/etc/gnucash/environment. But if you specify <prefix>
to be /opt/... or /usr/... in which case the <prefix> part is dropped and it
goes to /etc/opt or just /etc respectively (see
https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html). The defect in
GnuCash's code is that it doesn't trap that SYSCONFDIR adjustment so it doesn't
load the environment file, doesn't set GNC_MODULE_PATH, and so can't find the
modules.
