Personally I use aptitude for all Debian package management – Ubuntu and Mint
are the same as Debian really in this but with different package repositories.
Some people use apt and some apt-get, etc. For me the advantage of aptitude is
that it has a curses-based GUI as well as command line.

I am using the GtkD package created by the D Debian package people. This is
created using LDC rather than DMD. All the other libgtkd3 packages are ones
build by Jordi Sayol on D-Apt. If you want to use DMD, it is probably best to
install them. Me, I am an LDC oriented person so am happy with the standard
Debian packaged GtkD.
The libgtkd-3-0 package contains just the runtime libraries, or library in
this case. This being Linux libraries are always shared objects (aka DLLs):
> dpkg -L libgtkd-3-0
/.
/usr
/usr/lib

/usr/share/doc/libgtkd-3-0/copyright
/usr/lib/x86_64-linux-gnu/libgtkd-3.so.0
The libgtkd-3-dev package contains all the files needed to build code
against GtkD.

The last file here is crucial since it is the file you link your code against
to get the version currently on this system. The file:
/usr/lib/x86_64-linux-gnu/pkgconfig/gtkd-3.pc
is critical since it tells the compiler where to look for stuff.

In this situation, I tend to use SCons as a build manager. I also use Meson,
but the /usr/lib/x86_64-linux-gnu/pkgconfig/gtkd-3.pc is, sadly, inconsistent
with the way Meson works, so you have to use a bit of a hideous hack to get
things working. That is for later not now.
So here is a "Hello World in D" project I have:
|> tree
.
├── cmake-d -> /home/users/russel/Repositories/Git/Forks/CMake-D/cmake-d
├── CMakeLists.txt
├── dub.sdl
├── dub.selections.json
├── meson.build
├── SConstruct
└── source
├── gtkd_button.d
├── gtkd_label.d
├── qtd.d
├── SConscript
└── text.d
1 directory, 11 files
The CMake-D build is broken, so we have to ignore that.
The QtD is a work in progress, that isn't actually progressing.
Let me point you at https://bitbucket.org/russel/helloworld/src/default/D/
rather than cut and past the SCons files here. The summary is a SCons file is a Python script (Python 3.7 in my case) that calculates a build ADG and then actions any needed changes. The result in this case:
|> scons
scons: Reading SConscript files ...
scons: done reading SConscript files.

ldc2 -of=Build_SCons/text Build_SCons/text.o
scons: done building targets.
The calls to pkg-config have picked up the needed -L-L and -L-l options in
order for it to build.
I had thought the Dub build worked, but it doesn't. :-(

Sort of. Using the Debian packages, things get updated when the packagers
update things. They are usually pretty quick. Using Dub, you have to bit more
hands on given the dependency version in the dub.sdl file.

Hopefully the above has helped, do feel free to ask further questions. I am a
day-in, day-out Debian Sid user and so may still be making assumptions tht
aren't working for you…
