Adapt the Visual Studio project files to output the introspection files
in the same directories where the built binaries are located from the
previous patch.
Also, make the gtk3-introspect project dependent on the gdk-3 and gtk-3
projects only, so that we can build the introspection files without
needing to finish the whole build process. In order to "install" the
built introspection files, the gtk3-install project is now where this is
being done. Note that the introspection builds is still not built by
default at this point.
This is so that it is easier for one building GTK+ with Visual Studio to
build the introspection files as well in one shot. Note that this is
not built by default, so one needs to select the gtk3-introspect
explicitly to build (and clean up) the introspection files.
For this to work, one needs to ensure the following:
-A complete build of GObject-Introspection in $(GlibEtcInstallRoot),
that is built with the same installation of the Python interpretor that
is used here (see PythonDir and PythonDirX64 in
gtk3-version-paths.[vsprops|props]).
-Introspection files for ATK, GDK-Pixbuf and Pango, also in their proper
locations under $(GlibEtcInstallRoot), which should be built with the
same G-I installation.
Consolidate the .lib's that we need to link to for GDK and GTK+ into the
property sheets, and also link to setupapi.lib as that is needed by
the port to the new GdkMonitor API.
Search also for the headers in include/gio-win32-2.0, as gio.h will
include those headers at some point, and arrange the include paths in a
dependency hierarchy style, top-to-down.
We need to rename the projects so that when these projects are added
into an all-in-one solution file that will build the GTK+ 2/3 stack,
the names of the projects will not collide with the GTK+-2.x ones,
especially as GTK+-2.x and GTK+-3.x are done to co-exist on the same
system. This is due to the case that the MSVC projects are directly
carried over from the GTK+-2.x ones and was then updated for 3.x.
We still need to update the GUIDs of the projects, so that they won't
conflict with the GTK+-2.x ones.
