autokernel使用问题 #23
Description
1.Halide.h里面用到了c++17，autokernel_plugin的builid.sh中修改-std=c++17才能编译通过
2.tools.py第175行{HALIDE_HOME}/halide-build/inclue出现了这个路径，不同于autokernel_plugin部分，HALIDE_ROOT代表halide项目源码地址，HALIDE_DIR代表halide的安装位置，建议统一下，这里指定{HALIDE_HOME}/halide-build，需要在源码安装的时候指定build目录名字为halide-build，不同人的习惯可能不同。
3.tools.py第64行，{HALIDE_HOME}/bin这个bin目录源码位置没有（可能是Hailde拉取的版本不同），同时安装目录的库存放地址应该是{HALIDE_DIR}/lib
4.执行python3 tools.py --gen ../generator/batch_matmul.cpp -autotune -compute_time
出现错误：
