As discussion in [YOCTO #14717] cmake contains a OEToolchainConfig.cmake
file to configure the toolchain correctly in cross-compile build for recipes
using cmake.
The variable CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES value updates incorrectly
during do_compile the code. Due to this getting sporadic error like below,
fatal error: stdlib.h: No such file or directory
| 75 | #include_next <stdlib.h>
| | ^~~~~~~~~~
| compilation terminated.
| ninja: build stopped: subcommand failed.
| WARNING: exit code 1 from a shell command.
As cmake already correctly initializes the variable from environment,
So we have to unset it in the toolchain file to avoid overwriting the
variable definition again.

When building using an SDK, cmake complains that the target
architecture 'cortexa53-crypto' is unknown. The same build in bitbake
uses the target architecture 'aarch64'.
Set CMAKE_SYSTEM_PROCESSOR the same as for bitbake.

As discussied in [YOCTO #14717] cmake contains a OEToolchainConfig.cmake
file to configure the toolchain correctly in cross-compile build for recipes
using cmake. The CMAKE_ASM_FLAGS are the configuration are meant for assembly,
but the spelling is incorrect and the Flag is ASFLAGS for gcc and other compilers.
So this variable might neever have worked and it is better for
recipes to specify their own.

As discussion in [YOCTO #14717] cmake contains a OEToolchainConfig.cmake
file to configure the toolchain correctly in cross-compile build for recipes
using cmake. The variable CMAKE_LDFLAGS_FLAGS is spelled incorrectly, cmake expects
CMAKE_SHARED_LINKER_FLAGS, CMAKE_STATIC_LINKER_FLAGS, CMAKE_EXE_LINKER_FLAGS and
CMAKE_MODULE_LINKER_FLAGS to be set instead. As cmake already correctly initializes
these from environment there is no need to specify the linker flags in the toolchain
file at all. So this just removes the variable, as its value was also set wrong.

Use path from CMAKE_CURRENT_LIST_FILE to load the cmake subscripts.
This allows the toolchain file to be chainloaded from another toolchain file.

I am not sure why we do this in the first place, but it is causing
cmake to erroneously pick up items from the native sysroot
when building for the target and the target item is missing, for example:
https://autobuilder.yoctoproject.org/typhoon/#/builders/59/builds/198/steps/7/logs/step2c
Note that for executable programs this variable is not referred to,
as set by
set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER )
in the same file.

Setting CMAKE_SYSROOT in the toolchain file allows CMake to correctly
remove user-provided system include directories pointing to
<sysroot>/usr/include. The mentioned projects failed with "stdlib.h:
No such file or directory #include_next <stdlib.h>".

CMake, in it's infinite wisdom, when searching for libraries (using
find_library) will look inside the libraries PREFIX/lib, PREFIX/lib32, and
PREFIX/lib64. In a multilib SDK more than one of these will exist (potentially
all three) and obviously for a given build configuration only one of those is
valid. This search path is hard-coded deep inside CMake but by setting
CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX we can bypass it and set an explicit
lib<SUFFIX> to use.
Do this by writing ${baselib} into the environment file, and then stripping
"lib" from this to obtain the suffix in the cmake-specific environment script,
which is then read in the CMake toolchain.

The missing underscore makes CMake define a new variable named "CMAKE"
with the contents "ASM_FLAGS ${CMAKE_C_FLAGS}" instead of a variable
named "CMAKE_ASM_FLAGS" with contents equal to "CMAKE_C_FLAGS". It seems
clear that the intention was to assign "CMAKE_ASM_FLAGS".
CMake uses variables named "CMAKE_<LANG>_FLAGS" for defining default
compiler flags for a given language <LANG>. Leaving this flag unset may
have unintended consequences. Not doing so is however not an error as
far as CMake is concerned so it is silently accepted.

The previous string manipulations would result in the wrong string being used
for machines such as intel-corei7-64 as the sysroot was split at the first
hyphen (so would result in corei7 instead of corei7-64).
Change the logic so that it looks for processor-distro-os and uses the whole of
the processor field.

The other CMAKE_FIND_ROOT_PATH_MODE_* variables were already set to ONLY, but
PACKAGE was left out. Fix this so that cmake doesn't look on the host for cmake
modules when it should only be looking in the target sysroot.

This patch adds a flexible way to configure the CMake in SDKs. It adds
a toolchain configuration script which supports subscripts for
extensions, as for example Qt5.
