[gobject-introspection] Add README.txt files for Visual C++ builds

[Colin Walters <walters src gnome org>]

commit 7ff50ac3eb91c1bddb9e4f16f39af9c9ad96a739
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Mon Aug 13 16:14:29 2012 +0800

    Add README.txt files for Visual C++ builds
    
    Add instructions to tell people how to build gobject-introspection with
    Visual C++, especially as there are special steps and additional
    requirements for a successful build.

+Please do not compile this package (gobject-introspection) in paths that contain
+spaces in them-as strange problems may occur during compilation or during
+the use of the library.
+
+Please refer to the following GNOME Live! page for more detailed
+instructions on building gobject-introsecption and its dependencies
+with Visual C++:
+
+https://live.gnome.org/GTK%2B/Win32/MSVCCompilationOfGTKStack
+
+This VS10 solution and the projects it includes are intented to be used
+in a gobject-introspection source tree unpacked from a tarball. In a git checkout you
+first need to use some Unix-like environment, which will do the work for you.
+
+The required dependencies are Python 2.6 or later, GLib and LibFFI.  It is recommended
+that GLib is built with Visual C++ 2010 to avoid problems cause by usage of different CRTs
+
+Please refer to the README.txt file in $(GLib_src_root)\build\win32\vs10 on how to build
+GLib using Visual C++ 2010
+
+For LibFFI, please get version 3.0.10 or later, as Visual C++ build support
+was added in the 3.0.10 release series.  Please see the README file that
+comes with the LibFFI source package for more details on how to build LibFFI
+on Visual C++-please note that the mozilla-build package from Mozilla is needed
+in order to build LibFFI on Windows.
+
+For Python, retrieving the official Windows binaries for 2.6 or later from
+http://www.python.org will do the job-be sure that the Python version that
+you downloaded matches the configuration of your build (win32 or x64/amd64).
+
+For building the Regress test project, cairo (and possibly cairo-gobject support)
+is needed.
+
+Set up the source tree as follows under some arbitrary top
+folder <root>:
+
+<root>\<this-gobject-introspection-source-tree>
+<root>\vs10\<PlatformName>
+
+*this* file you are now reading is thus located at
+<root>\<this-glib-source-tree>\build\win32\vs10\README.
+
+<PlatformName> is either Win32 or x64, as in VS10 project files.
+
+For LibFFI, one should also put the generated ffi.h and ffitarget.h
+into <root>\vs10\<PlatformName>\include\ and the compiled static libffi.lib
+(or copy libffi-convenience.lib into libffi.lib) into
+<root>\vs10\<PlatformName>\lib\.
+
+The libintl.h that is used for building GLib needs to be in
+<root>\vs10\<PlatformName>\include, if not already done so
+
+You will also need a working GCC/MinGW compiler installation
+in order to generate the .gir and .typelib files.  One may be
+obtained from the mingw or the mingw64 project.
+
+A working pkg-config tool is also required-it may be obtained from
+http://www.gtk.org/download/win32.php [32-bit]
+http://www.gtk.org/download/win64.php [64-bit]
+
+*** Note! ***
+Please note that due to numerous possible configurations on Python, some environmental
+variables need to be set before launching the gobject-introsection.sln solution file.
+
+These variables are namely:
+PYTHONDIR: Root installation folder of your Python interpretor.
+           It must match your build configuration (Win32 or x64/amd64)
+PKG_CONFIG_PATH: Location of the .pc (pkg-config) files, especially for the GLib .pc files.
+MINGWDIR: Root installation folder for your Windows GCC (such as MinGW).
+*** End of Note! ***
+
+The "install" project will copy build results and headers into their
+appropriate location under <root>\vs10\<PlatformName>. For instance,
+built DLLs go into <root>\vs10\<PlatformName>\bin, built LIBs into
+<root>\vs10\<PlatformName>\lib and gobject-introspection headers into
+<root>\vs10\<PlatformName>\include\gobject-introsection-1.0.
+
+The generated .gir files will end up in <root>\vs10\<PlatformName>\share\gir-1.0
+and .typelib files will end up in <root>\vs10\<PlatformName>\lib\girepository-1.0
+
+This is then from where
+project files higher in the stack are supposed to look for them, not
+from a specific gobject-introspection source tree.
