This is done to be consistent with the GSettings
prefix (which is also a GLib subsystem).
In the process replace the magic string with
a single, globally defined macro.
They were only there due to how the source directories
are organized and not really adding useful detail.
Removing it from the resource paths gives more freeedom
wrt to the organization of source files.
This inverts the logic from
- having an xml file and extracting dependencies
from it to
- having a list of dependencies and generating
an xml file from it
In the original configuration adding or removing a
resource to/from the gresources.xml file would not
be detected by cmake as a change in dependencies.
The user would have to remember to rerun cmake manually.
By explicitly listing the dependencies, cmake will
properly recongifure and regenerate if that list is
updated. The remainder of the dependency configuration
also ensures proper rebuilds of gnucash, libaqbanking
and libofx if any of the resource files change, a new
one is added or an existing one is removed.
For reusability the code to generate the gresource related
files as been extracted into a separate function.
