Reference to libpng-1.6.38/configure,if enable_hardware_optimizations is
enabled, libpng can judge whether enable enable_arm_neon according
to $host_cpu.
----------------------------------------
$ cat libpng-1.6.38/configure
......
if test ${enable_hardware_optimizations+y}
then :
......
# allow enabling hardware optimization on any system:
case "$host_cpu" in
arm*|aarch64*)
enable_arm_neon=yes
printf "%s\n" "#define PNG_ARM_NEON_OPT 2" >>confdefs.h
......
