FASTBuild will replace `%1%` with
all the glob matches, which might
exceed command line limit on Windows.
Moreover, we don't need to pass all the
matches to the VerifyGlobs.cmake script.

Refactoring in commit 998495cb49 (cmExportCommand: Port to
cmSubcommandTable, 2025-07-15) accidentally removed support for the
`EXPORT_LINK_INTERFACE_LIBRARIES` argument. Restore it with a test.
Fixes: #27302
Add an explicit check in `install(EXPORT)` that the export name is
non-empty. Since an empty-named export set will never exist, this is
always an error. Previously, however, the error would not be caught
until generate time. Now an error will be produced immediately.

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.

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
This adds the following new arrays, which together capture all direct
dependencies and interface dependencies of a target:
- linkLibraries
- interfaceLinkLibraries
- compileDependencies
- interfaceCompileDependencies
- objectDependencies
- orderDependencies

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
When a variable ends with a newline, the Ninja generator escapes it as
expected with `$\n`. However, when writing it out, whitespace is
trimmed. This leaves a trailing `$` instead which consumes the newline
and masks the following stanza. In a custom command, this hides the
`restat = 1` setting.
Detect this case and restore the newline as necessary.
See: #25983
In commit 9d44a77454 (find_*: Explicitly normalize found paths as they
exist on disk, 2024-10-17, v4.0.0-rc1~597^2~1), we removed path
normalization from the internal `cmSearchPath::AddPathInternal` helper.
Most call sites were updated to normalize input paths first, but search
paths derived from `<PackageName>_ROOT` CMake variables are no longer
normalized. Instead we normalize the path to the file found after
searching.
When `find_package` "config" mode considers a candidate CMake package
configuration file, normalize its path before loading the adjacent
package version file so that the latter is loaded by absolute path.
Otherwise `cmMakefile::ReadDependentFile` interprets a relative path
with respect to the current source directory rather than the current
working directory.
