Include cmake feature module in the build routine
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.
