Build failed for arm64ec target architecture about sdl HOT 4 OPEN

Try running cmake with -DSDL_LIBC=ON. This is the default for SDL3, which was where I was reporting it worked in #8759.

from sdl.

cmake -G "Visual Studio 17 2022" -A ARM64EC -DCMAKE_SYSTEM_VERSION=10.0.22621.0 -DSDL_LIBC=ON .. 2>&1

CMake Warning:
  Manually-specified variables were not used by the project:

    SDL_LIBC

I tried it, but the same problem occurs(setup success and build failed).Maybe it's because of the SDL version? I'm using SDL2.I can provide steps to reproduce if necessary.

In #10312, ARM64EC detection is added and SDL_LIBC defaults to true for arm64ec.

With this GitHub workflow patch, I can confirm it works.
For current SDL2 releases (that don't know how to detect arm64ec), configuring with -DSDL_LIBC=ON should do the job.
I don't know why -DSDL_LIBC is considered non-used: it's here in the cmake script.

I couldn't test the -A ARM64EC integration because it is not available in current CMake versions.

Thanks for your answer. We will modify the build script soon and see if there are any problems.
