This also means when XCODE_SCHEME_WORKING_DIRECTORY is
set and a Xcode generator is used, that property will be used when
writing the debugger field in the file API replies.

In commit 7b19531291 (macOS: Do not pass any SDK/-isysroot to compilers
by default, 2024-11-06, v4.0.0-rc1~511^2) we broke support for using
upstream LLVM/Clang to build for macOS because the compiler has no
default sysroot. Handle empty `CMAKE_OSX_SYSROOT` with LLVM/Clang by
falling back to the macOS SDK reported by `xcrun --show-sdk-path` .
Fixes: #26863
Since KWSys commit `4feb470ab` (SystemTools: Remove GetActualCaseForPath
from CollapseFullPath, 2024-10-23), imported by commit ede7f2afa6 (KWSys
2024-10-24 (e1acde2e), 2024-10-24, v4.0.0-rc1~589^2~1^2), the KWSys
`CollapseFullPath` function that we use to normalize source file paths
no longer looks up the on-disk case of file paths. This change was
intentionally made to reduce unnecessary disk accesses. The change may
affect Windows-only projects that were never built on a case sensitive
filesystem. Call out the change in the 4.0 release notes.

In commit 7b19531291 (macOS: Do not pass any SDK/-isysroot to compilers
by default, 2024-11-06, v4.0.0-rc1~511^2) we forgot to update the
documentation of `CMAKE_OSX_SYSROOT`.
Fixes: #26846
Extend commit 1a35351125 (Add CMAKE_POLICY_VERSION_MINIMUM to help
configure outdated projects, 2025-02-13, v4.0.0-rc1~12^2) with an
environment variable to initialize the cache entry. That will make it
easier to use when `cmake` is invoked under layers of scripting.
Closes: #26715
Provide packagers and end users with a way to try configuring projects that
have not been updated to set their policy version to a supported level.
Closes: #26698
This allows projects to use `if(AIX)` blocks instead of spelling
out `if(CMAKE_SYSTEM_NAME STREQUAL "AIX")`. We already have similar
variables for many other platforms.
