The generator does a lot of tricks in order to make the "rebuild-bff"
target up-to-date immediately after the generation. We can skip all of
those during "TryCompile" runs, which should reduce configure time.
Refactoring in commit 3882718872 (VS: Decouple solution generation from
`.sln` file format, 2025-09-15) accidentally left out automatic
detection of the external project type id from its file extension.
Since commit c94f1bcf92 (Drop Visual Studio 7 .NET 2003 generator,
2017-04-19, v3.9.0-rc1~248^2) we no longer need special solution-level
target dependencies. We use `LinkLibraryDependencies` instead.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
Files listed in the `VS_SOLUTION_ITEMS` directory property of a project
directory are added as solution items in the 'Solution Items' solution
directory.
If `source_group` is applied to the files listed in `VS_SOLUTION_ITEMS`,
solution groups matching the names of the source groups are created
outside of the default 'Solution Items' group. If not items are placed
into the default group, it is not created.
Solution items added to subprojects are not included in the top-level
project.
Closes: #26409
* Add cmVisualStudioFolder struct containing names of projects within
that folder.
* Separate folder creation out of WriteTargetsToSolution into a new
CreateSolutionFolders function.
C++ modules have two variants which are of importance to CMake:
- `CXX_MODULES`: interface modules (those using `export module M;`,
`export module M:part;`, or `module M:internal_part;`)
- `CXX_MODULE_HEADER_UNITS`: importable header units
Creating C++ modules or partitions are *not* supported in any other
source listing. This is because the source files must be installed (so
their scope matters), but not part of usage requirements (what it means
for a module source to be injected into a consumer is not clear at this
moment). Due to the way `FILE_SET` works with scopes, they are a perfect
fit as long as `INTERFACE` is not allowed (which it is not).
Since commit f47b4f68a9 (Drop Visual Studio 7 generator for VS .NET
2002, 2016-03-10, v3.6.0-rc1~268^2), the `WriteTargetDepends` method has
not been used.
#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
This refactors a std::vector<std::string> into a class so that
we can extend the features to represent things such as multiple
chained commands in the future.
Make the constructors protected since they should be produced through
factories. Also rename `platform{ => InGenerator}Name` to clarify
the meaning of the argument.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

While we already support `cmake --build . -- -j`, the options after `--`
are specific to the native build tool. Add new options `--parallel
[<N>]` and `-j [<N>]` to abstract this and map to the proper option
for the native build tool.
We now require C++11 support including `override`. Drop use of
the old compatibility macro. Convert references as follows:
git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' |
xargs sed -i 's/CM_OVERRIDE/override/g'
