The value of the PROJECT_SOURCE_DIR variable is not always the source
directory of the "most recent project command". If the project was
included via add_subdirectory, variable scoping will prevent this
value to change in the parent scope.

Simplifies CUDA target architecture handling.
Required for Clang support as Clang doesn't automatically select a supported architecture.
We detect a supported architecture during compiler identification and set CMAKE_CUDA_ARCHITECTURES to it.
Introduces CMP0104 for backwards compatibility with manually setting code generation flags with NVCC.
Implements #17963.
The original wording was somewhat confusing in talking about rendering of
templates. While technically correct, a less experienced user may not know
that terminology. The wording has been updated to more clearly describe the
example usage.
The old way of implementing the example is not "bad", it was the only way to do
things before the CMAKE_CURRENT_FUNCTION_LIST_DIR variable was added.
The example has been updated to remove the Bad/Good captions to reflect this.
Indentation of the examples was also fixed to make them conform to the guidelines.
Also rename `..._DEFAULT_BUILD_FILE_CONFIG` to `..._DEFAULT_BUILD_TYPE`.
These name changes make the variables meaningful for future use by other
generators.
Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports
for both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we always export
all symbols from shared libraries by default. Add a new target property
called `AIX_EXPORT_ALL_SYMBOLS` that can be explicitly set to OFF to
suppress this behavior and export no symbols by default.

Replace our hard-coded default of cudart=static with a first-class abstraction to select the runtime library from an enumeration of logical names.

Add a `JOB_POOL_PRECOMPILE_HEADER` target property to specify the pool
name, and its associated `CMAKE_JOB_POOL_PRECOMPILE_HEADER` variable.
Fixes: #20217
Many users will want to use the Ninja Multi-Config generator like a
traditional Visual Studio-style multi-config generator, which doesn't
mix configurations - custom commands are built using target executables
of the same configuration the command is for. We do not want to force
these people to generate an N*N build matrix when they only need N*1,
especially if they have lots of targets. Add a new variable,
CMAKE_NINJA_CROSS_CONFIG_ENABLE, to opt-in to the cross-config build
matrix.
Original behaviour would unconditionally enable WinRT for all projects
so source file flag generation code can acknowledge WinRT being present
and disable it for C language source files. An unintentional result of
that approach is that WinRT is enabled for ALL projects, including C++
projects/source files with no way to disable it
Instead use `CMAKE_VS_WINRT_BY_DEFAULT` as a hint that the platform is
WinRT-by-default and set global `CompileAsWinRT` flag to `false` unless
it was explicitly requested by either `WINRT_COMPONENT` option or `/ZW`
compilation option - similar to what Windows Phone/Windows Store
platform logic does
In case WinRT compilation is enabled for a project by either of
aforementioned methods, C language source file override logic will still
kick in and disable CompileAsWinRT for C source files
Fixes: #20063
