Initial inclusion of GtkD
Outdated, latest release is 3.7.3
Only producing static libs, even though you specified shared so not sure whats going on there. We would like .so files instead of .a files.
After fixing the package to produce shared libraries, you may need to set libsplit : no so not only a -devel subpackage is produced.
You might find this spec file from opensuse useful
If tilix can be built with this as a local dependency for testing that would be great (dub add-local GtkD-3.7.3 & pkgconfig(gtkd-3))
That's quite a lot there so give us a shout if you need a hand with anything :)
