This allows C# UWP applications to use SDL2's SDL_WinRTRunApp function. Kudos to Ethan Lee (flibitijibibo@flibitijibibo.com) for the patch. Thanks!

/* At least one file in any SDL/WinRT app appears to require compilation
|
|
with C++/CX, otherwise a Windows Metadata file won't get created, and
|
|
an APPX0702 build error can appear shortly after linking.
|
|
|
|
The following set of preprocessor code forces this file to be compiled
|
|
as C++/CX, which appears to cause Visual C++ 2012's build tools to
|
|
create this .winmd file, and will help allow builds of SDL/WinRT apps
|
|
to proceed without error.
|
|
|
|
If other files in an app's project enable C++/CX compilation, then it might
|
|
be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW,
|
|
for Visual C++'s build tools to create a winmd file, and for the app to
|
|
build without APPX0702 errors. In this case, if
|
|
SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then
|
|
the #error (to force C++/CX compilation) will be disabled.
|
|
|
|
Please note that /ZW can be specified on a file-by-file basis. To do this,
|
|
right click on the file in Visual C++, click Properties, then change the
|
|
setting through the dialog that comes up.
