Description
1、libfacedetection-master主目录下默认的Cmake中只是配置了NEON，并无实际编译配置操作；
2、自己修改了Cmake，生成静态库并加入应用工程中，实测开不开SIMD（NEON）指令集对帧率几乎无影响

Research direction
Start with the default CMake configuration in the repository root and compare it with the reporter’s modified CMake setup for the static library. Reproduce the ARMv8-A application measurements with NEON enabled and disabled; done means determining whether NEON is actually compiled and explaining the reported lack of frame-rate improvement.
