Since commit 1ab3881ec9 (cmake: Add options for parallel builds to
--build mode, 2018-04-14, v3.12.0-rc1~42^2), `cmake --build --parallel`
has added two options to the msbuild command line:
* `/m` enables inter-project parallelism in msbuild.
* `/p:CL_MPCount=1` suppresses intra-project parallelism in cl.
The latter was used to avoid `O(N^2)` compilation threads on `N`
processors. In practice however, projects often have many source files
in a few targets, so `--parallel` actually reduces parallelism.
Drop the latter option to restore intra-project parallelism.
Users can always add `-- /p:CL_MPCount=1` themselves.

Enables the Global Visual Studio Versioned Generator to use two-part toolset versions,
if only one toolset has that version number. For example, (14.32 is specified when
14.32.32142 and 14.32.23242 are installed). This change also add a unique return code
and message if a two-part version is used when multiple matching versions are present.
Fixes: #23933
Revert commit a334f1b906 (VS: Write ZERO_CHECK.proj for VS19 and above,
2021-12-24, v3.24.0-rc1~607^2) and a supporting change from
commit 7219988b00 (VS: Exclude ZERO_CHECK.proj from .sln for
include_external_msproject, 2022-07-15, v3.24.0-rc4~1^2).
The change was made to support `dotnet` tooling in addition to
`msbuild`. However, not having `ZERO_CHECK` in the `.sln` breaks common
interactive workflows. Revert the change for now. Later it can be
re-introduced behind some kind of option that enables `dotnet` support.
Fixes: #23726
Issue: #20227
In `cmGlobalVisualStudio7Generator::WriteTargetsToSolution`, we skip
writing `ZERO_CHECK.proj` to solution file as the check in
`cmGlobalVisualStudioGenerator::IsInSolution` returns `false` for
`ZERO_CHECK`. However, we write ZERO_CHECK to ProjectDependencies for
external projects as there are no checks in
`cmGlobalVisualStudio71Generator::WriteExternalProject`.
Similar to `cmGlobalVisualStudioGenerator::IsInSolution`, we introduce
`IsDepInSolution(const std::string&)` which excludes `ZERO_CHECK.proj`
from being added to sln file for the cases where we have `ZERO_CHECK.proj`.
Fixes: #23708
Rename the booleans 's_ErrorOccured' and 's_FatalErrorOccured' to
's_ErrorOccurred' and 's_FatalErrorOccurred', respectively.
Rename the getters and setters to 'Get[Fatal]ErrorOccurred' and
'Set[Fatal]ErrorOccurred', and fix all uses across the codebase.
For VS 19 and above, switch the format of project file to
`VsProjectType::proj` for ZERO_CHECK target. The `ZERO_CHECK.proj`
consists of primitive MSBuild commands only and has no dependency on any
other targets or props files. This proj file is written as a
`ProjectReference` for other targets, but is not written to the sln
file.
Revert commit 925da7d428 (VS: Write ZERO_CHECK.proj for VS19 and above,
2021-12-24). Although its commit message was mistakenly not updated, it
implemented the change for VS 2017 and below too. Since it was merged,
I've discovered several subtle failures in nightly testing with VS 2017.
Revert the change pending further investigation.

* Extend Visual Studio solution parser for reading build target
* Map solution build target to project build target (especially for Any CPU)
* Use C++ <optional> template instead of pointer return value for cmSlnData::GetProjectByGUID
Add fields to the VS generator to select a target framework.
Migrate the existing default for VS 12 .NET CF for Windows CE.
Report the values in `CMAKE_VS_*` variables and use them for

Since commit 887e9df0c7 (VS: Update v142 CL flag table for VS 16.10,
2021-06-04) we map several `/external:*` flags to their corresponding
`.vcxproj` elements. These elements were added to `cl.xml` in VS 16.10,
so filter them out in older VS versions. Add a field to the json flag
table format to specify the minimum version of VS needed for a given
mapping.
Issue: #22308
Since commit 9054cd05e6 (VS: Add flag table entries for '/external:W*'
flags in VS 16.10, 2021-05-28, v3.20.4~10^2) we map flags to the
`ExternalWarningLevel` element. VS 16.9 does not support that element,
but its `cl` compiler does support the `/external:W*` flags. Filter out
the flag table entry on older VS versions.
Fixes: #22308
The names and formats of our VS flag tables are internal implementation
details. However, some institutions need to maintain support for
non-public VS platforms and toolsets. Provide a hook that their
projects can use to load custom flag table files. This helps avoid
distributing a custom CMake package within such institutions.
Document the hook itself, but explicitly specify that the files the
hook loads are not considered a stable interface.

CMake accepts the toolset version that is default in the current VS
version by matching the name later VS versions will use for the SxS
props files. It predicts the future name based on the first two
components of the current VS version's default toolset. However, this
heuristic breaks naming the VS 16.8 toolset version 14.28 under VS 16.9
because the latter's default toolset version is 14.28.29910, which did
not increment the second version component (unprecedented in VS).
Fix this by always using the requested version's SxS props file when it
exists, even if it matches the first two components of the current VS
version's default toolset. Also add a special case for the name VS
16.10 will use for VS 16.9's default toolset, so that it can be used
with VS 16.9 too.

VS 2017 version 15.8 introduced support for unity builds implemented
in part by the `$(VCTargetsPath)/Microsoft.Cpp.Unity.targets` file.
Do not enable unity builds on VS 15 versions that do not have that file.
