# winrtbuild.ps1 -- A Powershell script to build all SDL/WinRT variants,

#    across all WinRT platforms, in all of their supported, CPU architectures.

#

# Initial version written by David Ludwig <dludwig@pobox.com>

#

# This script can be launched from Windows Explorer by double-clicking

# on winrtbuild.bat

#

# Output will be placed in the following subdirectories of the SDL source

# tree:

#   * VisualC-WinRT\lib\  -- final .dll, .lib, and .pdb files

#   * VisualC-WinRT\obj\  -- intermediate build files

#

# Recommended Dependencies:

#   * Windows 8.1 or higher

#   * Powershell 4.0 or higher (included as part of Windows 8.1)

#   * Visual C++ 2012, for building Windows 8.0 and Windows Phone 8.0 binaries.

#   * Visual C++ 2013, for building Windows 8.1 and Windows Phone 8.1 binaries

#   * SDKs for Windows 8.0, Windows 8.1, Windows Phone 8.0, and

#     Windows Phone 8.1, as needed

#

# Commom parameters/variables may include, but aren't strictly limited to:

#   * PlatformToolset: the name of one of Visual Studio's build platforms.

#     Different PlatformToolsets output different binaries.  One

#     PlatformToolset exists for each WinRT platform.  Possible values

#     may include:

#       - "v110": Visual Studio 2012 build tools, plus the Windows 8.0 SDK

#       - "v110_wp80": Visual Studio 2012 build tools, plus the Windows Phone 8.0 SDK

#       - "v120": Visual Studio 2013 build tools, plus the Windows 8.1 SDK

#       - "v120_wp81": Visual Studio 2013 build tools, plus the Windows Phone 8.1 SDK

#   * VSProjectPath: the full path to a Visual Studio or Visual C++ project file

#   * VSProjectName: the internal name of a Visual Studio or Visual C++ project

#     file.  Some of Visual Studio's own build tools use this name when

#     calculating paths for build-output.

#   * Platform: a Visual Studio platform name, which often maps to a CPU

#     CPU architecture.  Possible values may include: "Win32" (for 32-bit x86),

#     "ARM", or "x64" (for 64-bit x86).
