Hi,

Thanks to Emmanuele for giving me the credit here :)

I should also mention that there are a few bugs underway to make the 
Meson build experience on Windows/Visual Studio better/working for the 
stack, which includes:
GLib: 783270 and 784995
ATK: 785802
Pango: 783274
GDK-Pixbuf: 785767
GTK+-4.x/3.9x: 785210 (Meson), 773299 (sources)

Any comments in those bugs are really appreciated, and thanks to all who 
have given pointers there, including Emmanuele, Bastien, Alejandro and 
Ignacio (and to those who I may have missed, sorry!)

Note that with the patches applied the Meson/Visual Studio builds are at 
least on par with the Visual Studio project builds, and GTK+-3.22.x 
builds (and I am quite confident as a result, 2.24.x builds as well), 
against the Meson/MSVC builds of the depedencies should be working 
equally well with the Visual Studio project builds.  Do note that 
though, for Ninja builds at least, --buildtype=debutoptimized will 
roughly correspond to the 'Release' configs in the MSVC projects (since 
we want the .pdb files), and the default buildtype (debug) will roughly 
correspond to the 'Debug' build configs in the MSVC projects.  It is 
highly recommended that Visual Studio project builds of items that uses 
the Meson/MSVC builds of these aforementioned items be re-built.

Please also note that there is a PR on Meson to fix introspection builds 
of GTK+ on Windows[1] due to the 8192-character-per-command limit on 
Windows, and Visual Studio 2008 support is not quite there for projects 
that still support it (i.e. for Python 2.7.x support, as that is built 
with Visual Studio 2008 for Windows), as we need to embed SxS manifests 
with 2008 builds.

With blessings, and cheers!
