If a gcc dep file is read that contains no dependencies,
cmReadGccDepfile returns a valid std::optional containing an empty
vector. Check at the call sites in cmDependsCompiler whether the vector
is empty before trying to access the vector's elements.

On some Xcode versions, `xcodebuild` may warn:
... xcodebuild[...] IDERunDestination: ...
Teach RunCMake to drop such incidental lines before matching against
expected output.
Backport commit edaa6ed06a (Tests: Teach RunCMake to ignore Xcode an
IDERunDestination warning, 2025-09-19, v4.1.2~9^2~1) to CMake 3.31.
KWSys's SystemTools::PutEnv implementation, on Windows, has long
interpreted `A=` as unset. This differs from the behavior on other
platforms. Code the distinction explicitly in `set(ENV{VAR})`.
Issue: #27285
The behavior differs by platform and if the variable is already set.
Encode existing behavior in tests to preserve it until intentionally
changed.
Issue: #27285
This adds the following new arrays, which together capture all direct
dependencies and interface dependencies of a target:
- linkLibraries
- interfaceLinkLibraries
- compileDependencies
- interfaceCompileDependencies
- objectDependencies
- orderDependencies
Fixes: #21995, #25213
Commit 62a1d3e7f1 (FileAPI: Add symbolic property to targets, 2025-09-30)
contained an error in added test code where a wrong library was linked.
The naming of the targets involved make clear the intended linking
relationship, but nothing in the test was actually testing or relying on
that relationship so it went undetected.
The cmLinkImplItem class used to contain some additional members
to support the CMP0027 policy. Since the CMP0027 policy and those
associated members were removed, the cmLinkImplItem class has been
a plain wrapper around cmLinkItem with no additional members.
It is no longer needed and cmLinkItem can be used directly wherever
cmLinkImplItem was used previously.
When targeting the MSVC ABI, define `_MBCS` by default if the project
does not define `_SBCS` or `_UNICODE`. Visual Studio has long defined
one of the three character set macros automatically. For consistency,
define it when compiling for the MSVC ABI with other generators.
Add policy CMP0204 for compatibility.
Fixes: #27275
