Thanks in advance.

This highly depends on your actual project:

- which 3rd party dependencies do you have
- are these dependencies d source code only or wrapping C 
libraries
- is the c source code of your dependencies available and you are 
able to create a static library of them
- does the license of the c dependencies allows static linking

Kind regards
Andre

I am trying to link the GTK library. I have the GTK Runtime 
installed on Windows 10 pc.

Do I need to build the static GTK library from the source? Then 
how do I tell DUB to include that library?

Unless things have changed in the last few years, GTK is not 
intended to be linked statically on Windows. You'll have to 
figure out how to compile it yourself as a static library. I 
recall reading about this a while back. IIRC, there were also 
some source changes required.

Then there's also the matter of licensing. GTK is released under 
the LGPL, which means if you statically link then your executable 
is considered a derivative work and must abide by the 
distribution terms of the LGPL.

 how do I tell DUB to include that library?

DUB has a "libs" directive in the build settings:

https://dub.pm/package-format-sdl.html#build-settings
https://dub.pm/package-format-json.html#build-settings

In dub.json:

"libs": ["exlib1", "exlib2"],

For any libexlib1.a or exlib2.lib, omit the extensions.

You can also do it like:
"lflags": ["-lstdc++"],

It may be extremely difficult if you intend to also link libc; 
the gethostbyname DNS functions in glibc do not support static 
linking.

OTOH you can create a fairly portably binary by static linking 
everything EXCEPT libc (I.e., do not pass -static flag to linker) 
— here you would need to link to the .a files of all your 
projects library deps as well as your dependencies dependencies...
