Error encountered while compiling for Arm platform

I got an error when compiling on arm platform

Consolidate compiler generated dependencies of target ncbi-bam

I guess it should be due to the wrong directory name. On arm, env.cmake includes interfaces/cc/gcc/aarch64 but what actually exists is interfaces/cc/gcc/arm64.

https://github.com/ncbi/ncbi-vdb/blob/34c611317dbe2832cf24ec543a95e9ca7b9eb2e6/build/env.cmake#L68-L71 https://github.com/ncbi/ncbi-vdb/blob/34c611317dbe2832cf24ec543a95e9ca7b9eb2e6/build/env.cmake#L158-L160

I renamed interfaces/cc/gcc/arm64 to interfaces/cc/gcc/aarch64 and everything looks fine.

Trivial solution would be to symlink cc/gcc/aarch64 to cc/gcc/arm64.

Note, gbench expects the directory to be called arm64 (gbench:build-system/configure.ac): aarch64:* ) vdb_inc_subdirs="cc/gcc/arm64 $vdb_inc_subdirs" ;;

-> Renaming breaks gbench.

Could you try it again with our last code?
