[Buildroot] [PATCH 1/1] package/sdl3: fix X11 dependencies

[Bernd Kuhls]

Add handling for optional X11 dependencies to fix configure errors:

CMake Error at cmake/macros.cmake:433 (message):
  Couldn't find dependency package for XCURSOR.  Please install the needed
  packages or configure with -DSDL_X11_XCURSOR=OFF

CMake Error at cmake/macros.cmake:433 (message):
  Couldn't find dependency package for XINPUT.  Please install the needed
  packages or configure with -DSDL_X11_XINPUT=OFF

CMake Error at cmake/macros.cmake:433 (message):
  Couldn't find dependency package for XSCRNSAVER.  Please install the needed
  packages or configure with -DSDL_X11_XSCRNSAVER=OFF

CMake Error at cmake/macros.cmake:433 (message):
  Couldn't find dependency package for XTEST.  Please install the needed
  packages or configure with -DSDL_X11_XTEST=OFF

Please note that SDL3 only checks for these dependencies when X11
support is enabled so we do not need to add =OFF options to the else-
clause -DSDL_X11=OFF:

Hi Bernd,

Thanks for the patch.

While trying this patch with the following commands:

cat >.config <<EOF
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_SDL3=y
BR2_PACKAGE_SDL3_X11=y
BR2_PACKAGE_XORG7=y
EOF
make olddefconfig
make sdl3

I had the following error:

CMake Error at cmake/macros.cmake:433 (message):
   Couldn't find dependency package for XFIXES.  Please install the 
needed
   packages or configure with -DSDL_X11_XFIXES=OFF

Could you have a look, please?

I did not checked if there is other instances of those dependency 
checks.
