When we make Visual Studio 2013 the baseline Visual Studio version, we need to
the *.vs12.sourcefiles that are generated along the way so that 'make distcheck'
won't complain about the leftover files. This was not caught in GLib as we do
not yet require Visual Studio 2013, but we update this here as this module is
intended to be used in projects that support Visual Studio project builds.
We are starting to require C99 features that can only be supported in
Visual Studio 2013 and later, so we need to prepare rules for Visual Studio
2013 to be our baseline version for Visual Studio builds, so that we can
move the templates from Visual Studio 2010 to Visual Studio 2013.
As this strives to be a shared autotools module between projects, there is
duplication at this point, though, because we still want to support
2008~2012 for projects that do not yet require the C99 features and depends
on GLib-2.50.x/GTK+-3.22.x or earlier.
Make the Makefile.am targets for generating the Visual Studio projects re-generate the
project files and the header listings whenever the Makefile.am's that include
build/Makefile.msvcproj changes, so that whenever a source/header is added, they will
be reflected in the projects and in the property sheets that are used to copy the
headers.
Also ensure that these are applied to the vs11, vs12 and vs14 projects when this
happens, as they are copied and processed from the Visual Studio 2010 projects.
This adds a common autotools module that can be used by various
projects to generate the Visual Studio projects as needed, and
if necessary, generate the headers listings to "install" for that
project, based on items passed in to this. This is modelled on the
Makefile.introspection autotools file that is used by many GNOME
projects to generate the introspection files.
