# AVX512 details: https://en.wikipedia.org/wiki/AVX-512#CPUs_with_AVX-512
#
# CPU features groups:

# ppc64le arch:
# VSX (always available on Power8)

# CPU_{opt}_SUPPORTED=ON/OFF - compiler support (possibly with additional flag)
# CPU_{opt}_IMPLIES=<list>
# CPU_{opt}_FORCE=<list> - subset of "implies" list
# CPU_{opt}_GROUP=<list> - similar to "implies" list, but additionally merges compiler flags
# CPU_{opt}_FLAGS_ON=""
# CPU_{opt}_FEATURE_ALIAS - mapping to CV_CPU_* HWFeature enum
# Input variables:
# CPU_BASELINE=<list> - preferred list of baseline optimizations
# CPU_DISPATCH=<list> - preferred list of dispatched optimizations
# Advanced input variables:
# CPU_BASELINE_REQUIRE=<list> - list of required baseline optimizations

#
# CPU_DISPATCH_FLAGS_${opt} - flags for source files compiled separately (<name>.avx2.cpp)
#
# CPU_{opt}_ENABLED_DEFAULT=ON/OFF - has compiler support without additional flag (CPU_BASELINE_DETECT=ON only)
