Compiler inspection relies on `try_compile`'s `COPY_FILE` option to copy
the `.wasm` file because the `.js` does not have the `INFO:size` string.
Issue: #27421
Extend commit e6aa7742b0 (VS: Generate .slnx files for VS 2026,
2025-09-17, v4.2.0-rc1~151^2) to add the `Type=` attribute on SLNX
`<Project>` elements.
Fixes: #27392
At the time of commit e6aa7742b0 (VS: Generate .slnx files for VS 2026,
2025-09-17, v4.2.0-rc1~151^2), the VS 18 Insiders edition did not offer
support for specifying a default startup project in `.slnx` files.
This has since been added, so use it.
Fixes: #27387
`include-what-you-use` diagnostics, in practice, are specific to
the environment's compiler and standard library. Update includes
to satisfy IWYU for our CI job under Debian 13. Some patterns:
* Types named in virtual `override` signatures no longer require
includes since the overridden signature already names them.
* A function argument's type needs to be included even if its constructor
is called only by implicit conversion. For example, constructing a
`std::function` from a lambda now requires `<functional>`.
* Some prior mysterious `<type_traits>` inclusions are no longer required.
Since commit 5420639a8d (cmExecuteProcessCommand: Replace cmsysProcess
with cmUVProcessChain, 2023-06-01, v3.28.0-rc1~138^2~8) we've
occasionally observed immediate timeouts on processes that take longer
than the timeout to start, even though we only start the timer after the
child processes start. The problem is that:
* `uv_loop_init` initializes `uv_loop_t`'s cached "now" time.
* Starting processes takes time but does not update the "now" time.
* `uv_timer_start` computes expiry relative the cached "now" time,
so short timers may be expired as soon as they are started.
* `uv_run` invokes expired timer callbacks before polling for I/O
or process completion, so we "timeout" immediately.
Fix this by updating the cached "now" time via `uv_update_time` just
before starting timers. This is needed only for timers that start
before the `uv_run` event loop. Update our `uv_timer_ptr` wrapper
to make all callers consider the choice when calling `start()`.
Check all instances of converting a JSON value to a string to ensure
that we check first if the value is convertible, in order to avoid an
exception being thrown, which crashes CMake. Modify some instances to
report when we encounter such invalid values. (Many instances, however,
just silently ignore invalid values.)

Improve how find_package reports the list of candidate package
configuration files that were considered but rejected to include a
reason for rejection. For CPS in particular, this allows the user to
tell if a CPS file was rejected due to a version mismatch, missing
required components, or because the file could not be read.
While we do not try to report more detail for why cmPackageInfoReader
rejected a file, the possible reasons are usually easy enough to
distinguish:
- The file is so malformed that we cannot read a JSON object.
- The schema version is not a version that CMake understands.
- The root object does not contain a string named "name".
- The root object does not contain an object named "components".
- Prefix resolution failed.
Three of these can only result from a file that fails schema validation.
Remove entries from the codespell ignore list that do not seem to be
present any more. Also, remove a deliberate typo and instead add a local
annotation to ignore it.
This list is still uncomfortably long, but unfortunately current
versions of codespell do not offer any granularity in between annotating
individual uses (which is not practical in most cases) or globally
ignoring words (which is overly broad and risks missing real errors).
Clang 21 now enforces placement of the module declaration:
.../scan_properties/module.cxx:7:8: error: module
declaration must occur at the start of the translation unit
Adds a "Step 0" to the tutorial which discusses minutia about where to
get CMake, how to run it, and most importantly deals at length with
various generator issues which aren't covered elsewhere.

Give the actual exit code of the command from the snippet as intended;
currently, this always gives 0 for sub-commands like compile and link,
as well as `ctest`.
For now, the result in build snippets will be `null`.
When CPS export fails due to a dependency on an improperly named
external target, reiterate the "canonical namespace" in the error
message for clarity.
When given the name of a project that doesn't exist, report it as an
"unknown project" rather than an "invalid project". This is more
consistent with other, similar reporting.
Add an explicit solution-level per-project `Platform` for `.csproj`
projects even if it is the same as the solution-wide `Platform`.
Otherwise the VS IDE skips building it.

Modify CPS import to set the `SPDX_LICENSE` on imported targets using
the specified package `license`, if present (and if none of the other
mechanisms for setting a license apply).
