As glib-mkenums would likely be used in the building of the other
components of the stack, such as Cogl, Clutter and
gsettings-desktop-schemas, generate that using a Python script (if Python
can be found) and "install" it.
Make the projects include a single property sheet as necessary, which will
in turn include the other property sheet(s) as needed, so that we can avoid
warnings where we include the same property sheets twice in a single
project.
Also make the copying of pre-configured headers into custom build rules so
that they can be removed upon the clean command from the IDE and that they
can be re-copied if their counterpart *.h.win32 are updated.
Install the Python scripts that is used by gdbus-codegen in
share\glib-2.0\codegen, to be consistent with the other platforms.
Please see https://bugzilla.gnome.org/show_bug.cgi?id=702862 for details
on this.
Split the property sheet into four sheets, to make maintainance of the
build files easier, and also to prepare for using autotools to fill in
the parts for the "installation" of headers.
Also put more of the items that are repeated in the projects into the
property sheets, also to improve ease of maintenance.
Updates to the Visual Studio 2010 projects will come later, as the script
to update them to Visual Studio 2012 must also be taken into account during'
the process.
