Also revert commit 9702a01dc9 (Help: string(LENGTH): Fix synopsis link
to command description, 2023-12-30, v3.28.2~23^2). It was only needed
to avoid re-using a named reference that we've now removed.
Issue: #25546
Xcode by default targets the SDK's macOS version rather than the host's
macOS version. In commit 7b19531291 (macOS: Do not pass any
SDK/-isysroot to compilers by default, 2024-11-06, v4.0.0-rc1~511^2) we
reverted commit 24aafbde11 (Xcode: Adjust deployment target SDK version
to host version, 2015-10-11, v3.4.0-rc2~6^2), but it is still needed for
Xcode. Restore the behavior so binaries run on the host by default.
Fixes: #27309
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.
Fixes: #26909
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.
Issue: #26854
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
In commit 84996a65aa (Unity: Add option to use relative paths for unity
files, 2024-10-15, v4.0.0-rc1~637^2) we added support for this variable
to initialize the `UNITY_BUILD_RELOCATABLE` target property, but forgot
to document it.
Issue: #26352
The module was deprecated by commit 7e2aee4458 (FindGDAL: Document as
deprecated in favor of upstream CMake package, 2024-11-26,
v4.0.0-rc1~409^2). Move the module to the list of deprecated modules.
Issue: #26471
