Some projects might get unlucky and have targets which collide in the
sha3-512 hash (truncated to 4) in a directory which also collides in the
same way (easily done by sharing it). Note such problems as potentially
colliding and offer potential remedies.
Also add a test which generates the error.
Closes: #27465
Find MSVC tools in VS 2026 installation.
This was missed in commit 3392b371 (VS: Add Visual Studio 18 2026
generator, 2025-08-20, v4.2.0-rc1~165^2~1). Follow the pattern from
commit 235b5fb05b (file(GET_RUNTIME_DEPENDENCIES): Support VS 2022
without VS 2019, 2022-05-19, v3.21.7~3^2).
Fixes: #27511
Modify the implementation of policy CMP0199 to only remove the oddball
configuration map matching of `$<CONFIG>` in `NEW` mode, restoring the
old behavior of matching BOTH the consumer's configuration and the
selected configuration of the imported target. It turns out that users
are more dependent on the former than the latter, and while matching
more than one thing is still dodgy, we will likely need to introduce a
new generator expression to match the selected configuration of the
imported target.
Meanwhile, `$<CONFIG>` on targets imported from CPS still only matches
the selected configuration of the imported target, which is the behavior
specified by CPS. However, this can only happen for `$<CONFIG>`
expressions that were generated internally during import.
Update documentation and test cases accordingly.

CMake 4.1 and earlier did not issue an error if an imported shared library target
was missing an IMPORTED_IMPLIB property and nothing used that imported
library. There was no code path checking for the CMP0111 NEW behavior. Since
b626843d71 (fileAPI: Output all INTERFACE and IMPORTED targets, 2025-09-13),
we now include all imported targets in the file API replies, and that does trigger
that check. We need to tolerate such imported targets to preserve backward
compatibility, and to avoid issuing errors for problems in targets likely to be
coming from outside the project and beyond the developer's control.
Fixes: #27496
Restore conditions broken by commit 19a61e56cf (VS: Refactor MSVC
character set selection, 2025-10-10, v4.2.0-rc1~12^2~1). We had misread
the purpose/scope of the `<= cmStateEnums::OBJECT_LIBRARY` condition.
In the original code it was only about safely indexing `ClOptions`,
not about the kinds of targets that can use a unicode character set.
Fixes: #27490
When a timeout is updated during runtime (e.g., via
`TIMEOUT_AFTER_MATCH`), the actual timeout needs recomputed based on
consideration of `StopTimeout` as well. Instead of using `Timeout`
directly, add a `GetComputedTimeout` method which also retrieves the
timeout reason based on which timeout is selected.
Avoid using `filesystem::path` to hold the output path. It performs
encoding conversions that violate our internal UTF-8 encoding.
Fixes: #27471
Issue: #27472
In commit 99d09ec45a (VS: Suppress MSBuild default link flags not
specified by project or user, 2025-06-17, v4.1.0-rc1~6^2) we removed our
default `-subsystem:...` link flag from `SHARED` and `MODULE` libraries
in Visual Studio generators for consistency with command-line generators.
However, unlike other flag suppressions for #27004, this change did not
just suppress MSBuild defaults, but actually changed flags the generator
was previously adding itself.
For the linker subsystem flag, consistency across generators should
perhaps achieved by adding the flag in other generators instead of
removing it from Visual Studio generators. Restore the previous
behavior pending further investigation.

In commit e419429616 (StdIo: Restore Windows Console I/O modes on
Ctrl-C, 2025-11-26, v4.1.4~4^2) we relied on the compiler to generate a
lambda with an `operator()` for each calling convention. MSVC does
this, but the GNU compiler for MinGW does not seem to.
Only force a compile PDB directory when PCH reusing. This avoids
affecting behavior in unrelated situations. However, PCH reuse requires
a known path so that the `copy_idb_pdb` logic can accurately generate
the copy instructions so that MSVC's rule that PCH use must use the same
PDB file can be adhered to.
Also revert the test suite adaptations from commit f78f592b78 (pchreuse:
defer target existence enforcement to generation time, 2025-06-16,
v4.2.0-rc1~481^2~4).
Fixes: #27401
When we pass a PDB output directory to the compiler in a path that
requires quoting, the trailing backslash must be escaped to be parsed
correctly by the compiler, e.g., `cl /Fd"path\with space\\"`. However,
`fbuild` does not parse this correctly when extracting `/Fd`. Work
around that bug by using a trailing forward slash in quotes instead.
Since commit 7db3dbddb2 (VS: Suppress MSBuild default flags not
specified by project or user, 2025-06-02, v4.1.0-rc1~69^2) we suppress
the `-Zc:inline` default flag when the project/user does not specify it.
That triggers an apparent bug in VS 2019 with v142 toolset versions
before 14.29 in which MSBuild fails when both `-Zc:inline` and `-nologo`
are suppressed. This happens when `CMAKE_VERBOSE_MAKEFILE` is enabled,
such as in `try_compile` projects like our builtin compiler inspection.
Since `-nologo` is incidental, avoid suppressing it if `-Zc:inline` is
also suppressed. Limit this workaround to relevant toolset versions.
Fixes: #27439
Revert commit 1a8712d31a (cmGeneratorTarget: always provide a compile
PDB filename, 2025-11-24). It changed our long-standing conditions for
when a naming a compiler-generated `.pdb` file is explicitly named.
It also caused some `BuildDepends` and `RunCMake.BuildDepends` failures
in VS builds that went unnoticed before merging.
Issue: #27401
Remove literal text "subcommand" from error messages. This addresses the
other use of this and improves consistency (see preceding commit). Also,
omit some unnecessary articles, which also improves consistency.
