CMAKE_REQUIRED_FLAGS now notes that space-delimited string, not
;-list is required, which could be surprising compared to similar
options that do use ;-list
Revert commit 5b45a3d0ce (CheckCompilerFlag: Match the Clang "argument
unused" output for all languages, 2023-01-23, v3.26.0-rc1~38^2). It
broke existing projects that were silently tolerating unrelated unused
arguments in their checks for C and CXX. For example, using
`CFLAGS=-nostdinc` or `CXXFLAGS=-nostdinc++` causes those flags to be
used when driving the linker as well, and Clang warns they are unused in
that case.
Add a test case covering the now-restored behavior.
Fixes: #24591
GenerateExportHeader had a hidden state requirement that other
modules were included first. Considering include_guard, Modules
should include all they actually use.
FindCUDA's custom commands invoke `nvcc`, which invokes `cl`. Under VS
this is done without a `/FS` flag, so `.pdb` generation races if we
use `BuildInParallel`. The FindCUDA module has already been removed by
policy CMP0146 after being deprecated since CMake 3.10, so it is
simplest to just disallow this combination of features.
Issue: #24576
These extensions are used by convention for C++ module interface units
with Clang.
For now, do not add any tests using these extensions.
Very few compilers recognize them as C++ sources.
Tests can be added later as part of C++ modules support.
The `FindCUDA` module has been deprecated since CMake 3.10.
Add a policy to pretend it doesn't exist in order to encourage
projects to port away from it.

Fix a regression from commit 073dd1bd81 (GoogleTest: Change format for
typed tests, 2022-02-07, v3.23.0-rc1~4^2) in the suite name detection.

Revert commit 66b5d51f38 (ExternalProject: Install CMake projects
using 'cmake --install', 2022-09-08, v3.25.0-rc1~150^2).
It changed the ExternalProject install step command from:
cmake --build <dir> --target install --config <cfg>
to:
cmake --install <dir> --config <cfg>
The latter command no longer runs the external project build system
during the install step. We could consider using the commands:
cmake --build <dir> --target all --config <cfg>
cmake --install <dir> --config <cfg>
as the install step, but if `CMAKE_SKIP_INSTALL_ALL_DEPENDENCY` is
used in the external project, that can change semantics too.
Revert the original change pending further investigation on other ways
to support its motivating use case. Add a test covering the
previously-regressed use case.

Since commit f24e34975a (ExternalProject: retry download on recoverable
errors, 2020-08-08, v3.19.0-rc1~298^2~1) ExternalProject has a list of
curl errors which trigger a retry today: 6, 7, 8 and 15.
Add curl error 28. It is a "timeout error", and should also trigger a
retry attempt at a download of an external project. The complete list
of curl errors is https://curl.se/libcurl/c/libcurl-errors.html
