If I don't include this change then I am not able to build cmake-native package at my end. I am getting compilation failure with cmake-native package as following:

build/tmp/work/x86_64-linux/cmake-native/4.2.3/sources/cmake-4.2.3/Utilities/cmcurl/lib/idn.c:37:10: fatal error: idn2.h: No such file or directory
   37 | #include <idn2.h>
      |          ^~~~~~~~
compilation terminated.
make[2]: *** [Utilities/cmcurl/lib/CMakeFiles/cmcurl.dir/build.make:1062: Utilities/cmcurl/lib/CMakeFiles/cmcurl.dir/idn.c.o] Error 1
make[2]: *** Waiting for unfinished jobs....
[ 29%] Building C object Utilities/cmcurl/lib/CMakeFiles/cmcurl.dir/llist.c.o

 

And just now, I checked and it is still failed. Are you able to build cmake-native package at your end without any failure?
