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.

Issue: #26123
In order to determine what character-set (Unicode, Multi-Byte, none)
shall be set in the generated `*.vcxproj` files, CMake checks if one of
the macros `_UNICODE` or `_SBCS` are defined.
However, as these macros can be defined with or without a value, the
check should always recognize these macros whether they are defined with
a value or without. That is now assured by this commit.
Fixes: #25379
If we add no CUDA architecture flags, write an empty `CodeGeneration`
field to tell the CUDA Toolkit's VS integration not to add its default
flags. We already use this approach for `CMAKE_CUDA_ARCHITECTURES=all`
so that the `-arch=all` flag can be added via `AdditionalOptions`.
Fixes: #23490
CUDA 11.6 added the `nvcc -arch=native` flag to automatically compile
for the host GPUs' architectures. Add support for specifying this
special `native` value in `CMAKE_CUDA_ARCHITECTURES` and
`CUDA_ARCHITECTURES`. During the compiler ABI detection step,
detect the native architectures so we can pass them explicitly
when using Clang or older versions of nvcc.
Fixes: #22375
The Visual Studio integration's CodeGeneration option only knows how to
generate a -gencode flag, which doesn't recognize all. Add a special case to
pass these two as regular additional flags.
When the VS 2010+ generators were first implemented in commit 7491f52992
(ENH: first pass at VS 10, can bootstrap CMake, but many tests still
fail, 2009-06-25, v2.8.0~546), the per-source preprocessor definitions
were placed before target-wide preprocessor definitions for consistency
with the behavior of VS 9 2008 and below. However, those generators
are not used much anymore. Instead prefer consistency with the order
used by the Ninja and Makefile generators.
Fixes#17559
Replace our hard-coded default of cudart=static with a first-class abstraction to select the runtime library from an enumeration of logical names.
Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
This adds the following functions to `cmStringAlgorithms`:
- `cmIsSpace`
- `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`)
- `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`)
- `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to
accept `cm::string_view`)
Add this generator *without* support for specifying the target
architecture in the generator name. cmake-gui will be taught
to provide a field for this, and command-line builds can use -A.
Also, teach this generator to select a default target architecture
based on the host architecture.
