-Please do not compile this package (GTK+) in paths that contain
-spaces in them-as strange problems may occur during compilation or during
-the use of the library.
-
-A more detailed outline for instructions on building the GTK+ with Visual
-C++ can be found in the following GNOME Live! page:
-
-https://wiki.gnome.org/Projects/GTK+/Win32/MSVCCompilationOfGTKStack
-
-This VS12 solution and the projects it includes are intented to be used
-in a GTK+ source tree unpacked from a tarball. In a git checkout you
-first need to use some Unix-like environment or manual work to expand
-the files needed, like config.h.win32.in into config.h.win32 and the
-.vcxprojin and .vcxproj.filtersin files here into corresponding actual
-.vcxproj and vcxproj.filters files.
-
-You will need the parts from below in the GTK+ stack: GDK-Pixbuf, Pango,
-ATK and GLib.  External dependencies are at least Cairo
-(with Cairo-GObject support, meaning Cairo 1.10.x or later), zlib, libpng,
-gettext-runtime, fontconfig*, freetype*, expat*.  See the 
-build/win32/vs12/README.txt file in glib for details where to unpack them.
-
-You will also need a Python 2.6+/3.x interpretor installed on your system,
-which can be obtained from the official installers available from
-http://www.python.org.  Please note that the Python interpretor (python.exe)
-either needs to be in your PATH before attempting the build of GTK+, or it
-can be found in the path specified by PythonPath in gtk-version-paths.props.
-If you happen to change the PythonPath setting in gtk-version-paths.props after
-opening gtk+.sln with Visual Studio, you will need to close the gtk+.sln solution,
-delete all the *.sdf, *.suo and *.user files before re-attempting the build.
-
-It is recommended that one builds the dependencies with VS12 as far as
-possible, especially those from and using the GTK+ stack (i.e. GLib,
-Cairo, ATK, Pango, GDK-Pixbuf), so that crashes caused by mixing calls
-to different CRTs can be kept at a minimum.
-
-To build with Vulkan renderer support, use the configs that end with _Vulkan.
-You will need the LunarG Vulkan SDK installed, and its include\ directory
-and Bin\ (64-bit) or Bin32 (32-bit) need to be in your INCLUDE and LIB paths
-(or need to be set in your additional include paths and additional library paths)
-so that they can be found by the build.  To run with the Vulkan renderer, set
-GSK_RENDERER=vulkan--you will need a video adapter with driver support for Vulkan
-to support this.
-
-zlib, libpng, and Cairo do contain support for compiling under VS12
-using VS project files and/or makefiles at this time of writing, For the
-GTK+ stack, VS12 project files are either available under
-$(srcroot)/build/vs12 in the case of GLib (stable/unstable), ATK
-(stable/unstable) and GDK-Pixbuf (unstable), and should be in the next
-unstable version of Pango.  There is no known official VS12 build
-support for fontconfig (along with freetype and expat) and
-gettext-runtime, so please use the binaries from: 
-
-ftp://ftp.gnome.org/pub/GNOME/binaries/win32/dependencies/ (32 bit)
-ftp://ftp.gnome.org/pub/GNOME/binaries/win64/dependencies/ (64 bit)
-
-Unzip the binaries obtained from ftp.gnome.org in <root>\vs12\<PlatformName>,
-and build the following, if not already done so: 
-
-Note: put the resulting zlib, libpng, pcre and Cairo files as follows:
- .dll files: <root>\vs12\<PlatformName>\bin
- .lib files: <root>\vs12\<PlatformName>\lib
- .h files: <root>\vs12\<PlatformName>\include
-
-The recommended build order for these dependencies:
-(first unzip any dependent binaries downloaded from the ftp.gnome.org
- as described in the README.txt file in the build/win32/vs12 folder)
--zlib
--libpng
--(for GDK-Pixbuf, if not using GDI+) IJG JPEG or libjpeg-turbo
--(for GDK-Pixbuf, if not using GDI+) libtiff
- [libtiff requires zlib and IJG JPEG or libjpeg-turbo]
--(for GDK-Pixbuf, if not using GDI+) jasper [jpeg-2000 library]
--(optional for GLib) PCRE (version 8.12 or later, use of CMake to
-  build PCRE is recommended-see build/win32/vs12/README.txt of GLib)
--GLib **
--Cairo (inclusive of Cairo-GObject)
--ATK**
--Pango**
--GDK-Pixbuf**
-(note the last 3 dependencies are not interdependent, so the last 3
- dependencies can be built in any order)
-
-The "install" project will copy build results and headers into their
-appropriate location under <root>\vs12\<PlatformName>. For instance,
-built DLLs go into <root>\vs12\<PlatformName>\bin, built LIBs into
-<root>\vs12\<PlatformName>\lib and GTK+ headers into
-<root>\vs12\<PlatformName>\include\gtk-3.0. This is then from where
-project files higher in the stack are supposed to look for them, not
-from a specific GLib source tree.
-
-Please note, as GTK+ uses the Adwaita theme for all platforms by default,
-most icons used are not included with GTK+ (which *are* needed), so please see
-https://live.gnome.org/GTK%2B/Win32/MSVCCompilationOfGTKStack (under the
-GTK+ section) on how to get those icons set up for use with GTK+.
-
-*About the dependencies marked with *: These dependencies are optional
- as those are not compulsory components for building and running GTK+
- itself, but note that they are needed for people running and building
- GIMP or those who need complex script support via fontconfig.  They
- are referred to by components in Cairo and Pango mainly.
- Decide whether you need fontconfig support prior to building Cairo
- and Pango.
-
-**:Put the sources of the packages marked with ** in <root>\<package-
-    source-tree>, and build with VS12 from there.
