# set extensions (like SSE4.2, AVX, AVX2, AVX-512) and 
# if the compiler can generate code for those extensions. 
#If both conditions are met, it will enable the use of those extensions in the build,
# which can improve performance on compatible hardware. 
# If set to 0, it will not check for or use any host CPU instruction set extensions, 
# which can improve compatibility but may result in lower performance on modern CPUs.
