These headers come with the MS compiler. Some of them are standard, like emmintrin.h, others are MS specific like crtdefs.h
This separation will allow using MS CRT headers. Eventually it can allow compiling with the compilers' runtime headers.
- Add some of the missing CMake adjustments to continue the configure and compile process with ARM64 MSVC
- Created quick stubs for the functions in SDK needed to finish the configuration process
- Put in an ARM64 option for spec2def

Having conditional statements with CMAKE_BUILD_TYPE is an antipattern
See https://stackoverflow.com/questions/66079007/having-conditional-statements-on-build-type-variable-a-good-design
We use both single- and multi-config generators (Ninja and VS), so we
can't really rely on CMAKE_BUILD_TYPE, because it's not always set.
This commit alters some conditional flags to use <$CONFIG:...>
generator expression, but is still not complete. Also, our default
optimization level (4) now has what was always a de-facto flags
config*.cmake files are constantly getting out of sync between
each other. Besides that, the parameters are not really dependent
on a target architecture, but rather on a compiler (except *ARCH)
This approach seems to be more future-prone, and allows to see
all the options in one file (there are really not that many of them)
That way, we won't use whatever standard is the default on whatever compiler we are using.
This should also prevent using more recent features without warning.
- Updated toolchain file
- set GCC variable when using CLang in "GCC mode"
- Properly retrieve GCC support libraries
- Various flags needed to get this going
Instead of messing with global variables and the like, we introduce two target properties:
- WITH_CXX_EXCEPTIONS: if you want to use C++ exceptions
- WITH_CXX_RTTI: if you need RTTI in your module
You can use the newly introduced set_target_cpp_properties function, with WITH_EXCEPTIONS and WITH_RTTI arguments
We also introduce two libraries :
- cpprt: for C++ runtime routines
- cppstl: for the C++ standard template library
NB: On GCC, this requires to create imported libraries with the related built-in libraries:libsupc++, limingwex, libstdc++
Finally, we manage the relevant flags with the ad-hoc generator expressions
So, if you don't need exceptions, nor RTTI, nor use any runtime at all: you simply have nothing else to do than add your C++ file to your module

Sorry, but the negative impact for other devs and the
whole project are just unbearable.
Stuff got committed meanwhile even so I had to act.
The improvements may be reapplied later when the
negative consequences are under control.
Get rid of global properties and use a target-level properties instead
Limit temporary files by using cmake-generator expressions instead
Avoid function calls at the end configuration, use file(GENERATE) idiom instead
