Add predicate `ifFeatureEnables` that checks feature is define or not,
and return accordingly boolean value.
Consider some cmake objective targets as features. Populate information
to these targets, and provides in particular file `CMakeFeatures.txt`.
Cpuid, MSR, ACPI and driver VGA in text mode they are.

Cmake build type at the generation stage2026-03-28T07:55:53ZAlexey Gavrilovalexey.gavrilov@mail.com2026-03-28T07:55:53Zurn:sha1:378972285342f52bb71822d87ba261b76b4a42ed
Fix in *nasm* files - set architecture bitness.
Move compiler flags from *toolchain* file to *requirements target*
considering cmake files. This solution allows available of
multi-configurations generators to pass compiler options
without affecting on single-configuration generators.

- Debug information
- Image creation
- Build under window platform (optional)

Cmake build generator support: build stage2026-03-27T07:03:55ZAlexey Gavrilovalexey.gavrilov@mail.com2026-03-27T07:03:55Zurn:sha1:6ffe96d1e3f0289c2070e050cf8e1a30288e6d91
Multi-target architecture implementation:
each root source code directory presents the one
*INTERFACE* target to it's subdirectory subtargets
that link only as *STATIC* library.
For instance, *arch* directory presents *Architecture* target
then *Architecture* target has *CPUID*, *IO*, *PORT*
and etc. dependencies
Exact order of linking targets is: boot.o CRTIBUNDLE <TARGETS> CRTNBUNDLE.
Sequence destruction cause to UB. Please to pay attention to this.
TODO
- Debug information
- Build type
- Toolchain file
- Image creation
- Build by WinGW compiler on Windows platform (optional)

Put in cpuid some definitions and declarations2025-12-11T08:44:00ZAlexey Gavrilovalexey.gavrilov@mail.com2025-12-11T08:44:00Zurn:sha1:b98035306ceca38432c754847e3ef7474b1b778c
Declarations: `acquireInformation` for two extended cpuid
commands. Overloading `operator&` for enum classes in
`VersionInfo` structure to get proper bit value.
All declarations from ==Cpuid.h== file are define in the
corresponding cpp file.

Refactoring cpuid model interaction2025-12-01T14:40:49ZAlexey Gavrilovalexey.gavrilov@mail.com2025-12-01T14:40:49Zurn:sha1:75ef20c5889005758ed8c30c3279954f16529a16
Patch for support CPU identification feature.
Model smash on two pieces: platform-independent and dependent accordingly.
The first obtains architecture details from CPU by special registers or
execute instruction and filling proper structure. The second piece needs
for more universality to use in independent code.
Currently, platform-independent part supports only x86 cpuid(0h,01h) leafs.
