If we don't do that, the traversal of the sources list to generate the
sources file for g-ir-scanner is going to explode with a Python
backtrace like this one:
File "/usr/lib/python3.5/site-packages/mesonbuild/modules/gnome.py", line 463, in generate_gir
gir_filelist.write(os.path.join(srcdir, s) + '\n')
File "/usr/lib/python3.5/posixpath.py", line 89, in join
genericpath._check_arg_types('join', a, *p)
File "/usr/lib/python3.5/genericpath.py", line 143, in _check_arg_types
(funcname, s.__class__.__name__)) from None
if the sources list contains a list.
An example trace:
[snip]

> result = self.fn(*self.args, **self.kwargs)

On Windows, one will face the issue of the 8192-character limit for each
command line, so this will cause an issue when one is building items
like GTK+ with introspection, because the g-ir-scanner command line will
likely get too long, which will clearly break the build. This will
affect all Windows builds.
Make use of the --filelist option that is already in g-ir-scanner, and
generate such a file list from the sources that are fed to
generate_gir(), named as
$(builddir)/$(target_id)/<NameSpace>_<NameSpaceVersion>_gir_filelist
and using it during the build.
* add support for cups dependencies
libcups has its own cups-config tool rather than using pkg-config.
This adds support for cups-config, based on pcap-config and
sdl2-config implementations.
This change also includes the unit test case and documentation for
cups dependency object implementation, and libcups2 dep to CI image.
Actually, GDC supports shared libraries since version 6.2, but on Debian
there are still issues with that version due to the standard library not
being compiled with PIC.
Therefore, we make a very conservative assumption here and only enable
the tests for GDC >= 7.0
