Joerg Bornemann 7c3ca57b91 MSVC,Clang: Set CMAKE_CXX_COMPILER_PREDEFINES_COMMAND for the MSVC ABI 
The variable was only set by the GNU-like compiler modules, so AUTOMOC
never generated a moc_predefs.h for compilers targeting the MSVC ABI
and moc parsed headers without the compiler's predefined macros.

MSVC dumps its predefined macros with '/PD', which needs the conforming
preprocessor. Require VS 2019 16.8, because 16.7 and older ignore the
flag with warning D9002 and emit no macros at all. clang-cl takes '-dM'
through '-Xclang'. Both also echo the preprocessed source, so feed them
an empty translation unit. clang with the GNU driver is excluded from
'Compiler/GNU' as well when it simulates MSVC, so give it the usual
'-dM -E' command there.

Fixes: #28093

Marc Chevrier 00932ea864 Introduce CMAKE_<LANG>_LINK_MODE variable. 
This variable define how the link step is done. Possible values are:
* DRIVER: the compiler is used as driver for the link step
* LINKER: the linker is used directly for the link step.

Patrick H 373b29bd3f Rename {_ => }CMAKE_INCLUDE_SYSTEM_FLAG_${lang}_WARNING 
Although not documented publicly, projects may need to override
this variable.  Remove the private `_` prefix from its name.

Martin Duffy 76a08cd253 COMPILE_WARNING_AS_ERROR: Add options to treat warnings as errors 
Add `COMPILE_WARNING_AS_ERROR` target property and supporting
`CMAKE_COMPILE_WARNING_AS_ERROR` variable.

`COMPILE_WARNING_AS_ERROR` is initialized by
`CMAKE_COMPILE_WARNING_AS_ERROR`. It is a boolean variable. If it is
true, it expands to a different flag depending on the compiler such that
any warnings at compile will be treated as errors.

Supports compiler ids that I could find a relevant flag for.
