I let this be the more restrictive condition as I wasn't sure if any "MSVC like" compilers would support the version file, I'm not aware of any that do, so I think this suggestion is probably fine, but I'm not aware of the scope of Arrow's deployment, and just wanted to point out there are side effects from changing this check beyond terseness, just to be safe.

All MSVC like compilers behave like #50450 (comment) , right? (All symbols are hidden by default.)

If so, can we use elseif(MSVC) here?

# MSVC does not support version scripts, but check_linker_flag won't return false
# due to how MSVC's linker reports unrecognized arguments
set(CXX_LINKER_SUPPORTS_VERSION_SCRIPT FALSE)
else()
include(CheckLinkerFlag)
check_linker_flag(CXX
