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.
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.

Revise the change from commit 5a36d0c9e7 (Ninja: Fix regression with a
large number of subdirectories, 2025-03-04, v4.0.0-rc3~2^2) to use a
command-line length limit small enough for `.bat` files.
Fixes: #27153
* Use `uv_disable_stdio_inheritance` to resolve the deadlock between the
parent build system process and `ctest
--wait-and-collect-instrumentation` on Windows.
* Remove Windows gating from preBuild and postBuild indexing and update
tests and documentation accordingly.
Fixes: #26668
When the `MACOSX_PACKAGE_LOCATION` property is set on a directory, Xcode
copies the entire directory into the bundle. Implement this on Ninja
and Makefile generators too.
Fixes: #26808

Since commit f50fb77a4f (Ninja: Regenerate when test or install scripts
are missing, 2024-10-29, v4.0.0-rc1~516^2) the list of paths we pass to
`ninja -t restat` scales with the number of project subdirectories.
Run it in blocks to avoid "command line too long" errors, particularly
on Windows.
Fixes: #26738
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.

In commit 197cb419d1 (add_custom_command: Add CODEGEN support,
2024-05-27, v3.31.0-rc1~394^2) we accidentally left out the global
`codegen` target's dependencies on the per-directory `codegen` targets.
Add them for parity with the `all` target.
Fixes: #26517
Add a way to specify, in a portable way, to raise an error for any
warning during the link step. For that purpose, define:
* CMAKE_LINK_WARNING_AS_ERROR variable
* LINK_WARNING_AS_ERROR target property
Fixes: #25343
Rerun CMake when `cmake_install.cmake` or `CTestTestfile.cmake` are out
of date. This enables regeneration if a subdirectory is removed before
invoking `ninja`.

This is needed to inject arguments through flag generation mechanisms so
that they can all be unescaped uniformly. Eventually, these methods
should go away and the escape/unescape dance be avoided completely.
The function attempts to read the path to cmd executable from the
COMSPEC environment variable. Falls back to cmd.exe if the respective
environment variable is not set or path doesn't exist.
By specifying CODEGEN as an argument to add_custom_command the
custom command will be added to a codegen build target.
The intent is to provide a convenient way for users to get
their generated files without having to build the whole project.
This can be helpful for code analysis tools which can be useful
for IDEs and CI.
